Write website allofanything.com: Website of Free & Paid Lists

I need someone to write (and people to host and promote) a website that maintains free (anyone can see and add to it) and paid lists in a hierarchy of categories. Paid lists are private to the person who creates it and other users offer entries for a price with free random samples before purchasing. We can discuss/develop more details in a chat. Do you have a non-disclosure agreement? Charlie
