Building a company team is much more complex and revolves around your business plan. You need revenue projections along with employee costs to proceed. I would recommend you hire an experienced consultant to guide you or put together an advisory team/board of entrepreneurs who have started businesses and made them successful.
The concept plan will define your product/service and allow you to flesh out the idea. Key facets of this should at least include: a description of the website's function and a proposal of the value added to its users; a(n at least basic site map); a flowchart describing the process of building the site; and design and usability considerations.
The strategic plan will allow you to identify the business model you are expecting to employ. If done right, it should be straightforward (though sometimes difficult) to construct it in a way that connects the dots. In my opinion, every strategic plan should include: a description of your core principles as an organization (vision/mission/goals/values); an analysis of your internal resources and external market environment (not limited to your presumed customer base); strategic options and a description of your choice as well as an explanation of 'why'; a plan for implementation of the strategy - including needed resources; expectations of performance (operational/market/financial); a description of relevant metrics you can use to gauge your business' performance; and a plan for how to monitor and respond to changes in your operations and/or market.
Developing your team of core advisors and mentors is very important, as I'm sure you already know. It sounds like you need some advisors/mentors just for general business purposes - and at least 1 or 2 that specialize on the web side.
Just my opinion, but I'd start by scanning through your business plan to determine core areas needed to get your business going. That will help you determine what KIND of advisors you need. You are particularly looking for people with skills you don't have. As an example, I have an accounting degree, so when I was looking for core advisors, I did NOT look for an accountant, since I would fill that slot, myself. If you can interest a lawyer and someone with an accounting/finance background, that's a real plus. For web models, I'd also say a really energetic, up-to-date marketing person would be a tremendous plus. The marketing person should be very knowledgable about current and up-coming web and new media (like i-Phone, etc.), able to evaluate what is working, all the legal requirements, etc., since all of these will, ultimately, be a part of your big picture.
On the web side, someone very strong in web development from the IS side - and, if you can get two, one who is also strong on web commerce (if this will be an e-commerce site). I have discovered that some folks who are terrific at innovative web design and management aren't as strong on e-commerce, which has a lot of legal and technical areas that are vital.
Once you've figured out what kind of advisors and mentors you need - I'd say no more than 8-10 people with 6-8 people being ideal - you can start strategizing on how to get them!
Depending on where you live, an area university or your alma mater may have a program that matches graduate students in a specific area with projects. A law school may have a free law program similar to that. I live in Nashville, TN, and Vanderbilt University does both of these. It's not just for start ups - some really big companies use these services. If your alma mater has an online business connection, sometimes folks from your school might be interested and willing to help - or identify someone for you.
Another way is to become active in some organizations that people that you need are likely to belong to. I belong to the American Marketing Association for just that reason. Check FaceBook for professional listings. Some pros participate in FaceBook. Even if they aren't available for a low cost, they frequently can match you up with someone good who is - or you may find them by visiting a page frequently and observing their posts. I have met an excellent career coach through LinkedIn, for example.
Networking is a really big key, but it needs to be networking with people who have what you are looking for, not just social events and business-card-swaps. Don't be bashful about "telling your story" over and over again. Come up with a couple of short pitches (one 2 minute one and one 5 minute one) that will explain what you are trying to do. That won't bore the people who will eventually say, "Oh, yeah, I have a friend that would be interested in that" . . . or "does that" and will be willing to give you an e-mail or contact to get in touch with them. And, if they are interested themselves, they will let you know and you can go into more detail. A lot of this is really viral and on-the-spot. The big thing on networking is to have a plan. Plan 1) what you are going to; 2) who you want to talk to; 3) what you plan to say to them; and 4) what you are trying to get (contacts, etc.). You'll get better results that way.
A lot of cities have Small Business centers that provide a LOT of help with this. Check and see if there is one in your area. They are frequently free. And, many Chambers of Commerce have programs that can help, too. Some of the COC programs are free - some cost some money, but not usually very much.
Its a very dangerous trap "if I build it they will come". I've fallen into that trap myself in the past and paid in time and money. Validate your business model first.
Does your product address a pain point?
Is your pain point recognized?
Is the pain great enough that people are willing to pay for it? (I can't stress this point high enough)
Will the payment model support the business both in start up and as it grows?
Second prototype and model your product. You should take an iterative approach starting with detailed static mockups, framework functions, etc. and validate, validate, validate with leaders in the industries or markets you want to capture. I've found great value in paying a graphic designer to produce myriad static displays (in fine detail) so that I could "show" the functions and collect feedback early on. An additional benefit is the coding team will have a much better understanding of what the final product should look like and how it should behave. They will also insert a number of technical requirements that would be missed otherwise.
Warning... you need a graphic designer that has worked with a development team before. They need to inject realism in the static product. It would also be helpful to finalize your business requirements. What is the end product supposed to achieve. Which of course dove tails in the business modeling.
An additional point of warning. Off shoring can work very well particularly if you've managed other development projects and have a good understanding of the process, the requirements and acting as a business owner for a project. Off shoring has its negatives including language barriers, cultural misunderstandings, time zone craziness, cost barriers to face-to-face engagements and challenges in aligning business requirements to technical requirements. If you've never done this before and you want to try this approach, get someone to coach you who has experience with this.
Also http://www.8kmiles.com is a wonderful concept to pull in a team, virtually.
Do not believe in free tools, or pro bono work or free items / widgets. Build up from scratch, you might have sometime and something to show to VC's and Angels.
