Video Sharing Portal/Website + Billing System

We are interested in setting up a own webpage like YouTube or MegaVideo (own style), but we don´t want to be free, we want to charge money for the content other users have uploaded - just in case that the users watch more than 60 Minutes/day a message on the flash-player must appear like "Please pay if you want to watch more video...". A good recommendation was [login to view URL] for a sourcecode for a videosharing portal, which is available there for 200,- USD, but it doesn´t include a billing system. So what you should do is to imagine a portal like YouTube or [login to view URL] with a billing system where users have to pay for watching videos. Uploads can be made by everyone for free. We need a description of that what you would propose (based on the source code of [login to view URL], which is available to buy for own modifications and extensions) and stepstones you define, based on which we are paying. We also need to see some examples before and reference projects. The project will have a budget of 15.000 USD/year, where the V1.0 of the webpage including all with billing system and accounting should be made for 3000,- USD or even less. Please bid only if you really have good experience and good references which can be used and compared for skills in developing video-sharing websites.
