Startup Idea : Web application for finding team

This is web application which will be used for local competition in informatics. After the competition I would love to improve the application and make it usable for the general public. This web application would work this way: everyone can register and make a profile on it. You can state your personal information and projects you would like to work on as well as projects you have already finished. People can look over your projects and contact you about working on a specific project, give you some advice, even donations. After every succesful project, we would make sure that it gets to the market easily. I guess someone could help me with this :)
