Speaking Truth to Power: Programmers Required

I have an idea for a very successful business but do not know where I can find start-up capital to begin the project. The powers that be in the entrepreneurial community do not believe that the idea will work. I do believe that it will work because it provides a useful service for free to users. If you are a computer programmer and would like to build the proposed site for my company in exchange for being paid as future net profits accrue to the company I would be happy to meet with you to discuss the specifics of the project and to hammer out a service contract with you. It is my belief that the service I propose will take off just like Facebook. I look forward to hearing from all interested parties.
