Looking for web developer to launch idea

I'm working on an idea for small business. Looking for a talented web developer who can help with the back-end coding to launch the website. If you have the ability to code a website with the same level of interactivity that social networks have then you would be suitable for this project. It would be part time coding and I'm looking for someone who would be willing to cooperate in the project (so unpaid for now). Once the site is launched and is generating revenues there will be returns. If interested please contact me so we can talk more about it.
