Mixture of NiteFlirt.com and Facebook.com

Project Description:
I'm venturing into creating an adult website which allows users to buy pictures, videos, clothing, audio, and other items from other users. I want it to be similar in the way NiteFlirt.com operates but I want to integrate a social aspect to it, similar to Facebook.com. I have already designed the look of the website and just would need someone to put my ideas and model to a functioning code. We would have CCBill or Authorize.net handle the credit card transactions. Thus, in summary, I'm looking for a website very similar to Facebook, where users can interact with each other, add friends, and post media but at the same time be a website with the adult aspects of NiteFlirt.com where users have the option to buy items from other users who would be independent contractors on the site offering adult content. I have included a general design of the site which I would like to be followed.
