Clips4Sale.com Clone ( not for porn )

NO this isn't gonna be a porn site! :) I want to make a site where users can post up video game art tutorial video's and sell them. I run [login to view URL] and would like to expand it's services to include allowing users to post their own videos. I already have client base for this. The site will work very much the way [login to view URL] works. Users can upload video's, categorize, and price their video's. Other users than can come, pay money, download the video. Part of the money would go into a the authors account...another part into the companies account...and another part into your pocket. Payment should happen via paypal. I will share revenues as well as pay you for your work on the site. 15% of all profits on the site will go into your pocket ( other terms to be discussed ) I will supply all graphics and UI direction. You are responsible for code. Only serious bidders need apply.
