_________________I need a video sharing based website

Here's the deal, basically i need a [login to view URL] type of website. Something where you can upload view and share video files. This site needs a free user area, that area needs to only have videos that the administrators can upload, not the general public. Then the site needs to have a members area, where they have to pay a membership fee to acess it. In this area they can upload their own videos, signing an electronic agreement that the video they are uploading is soley owned by them and they have the right to upload it, furthermore that by uploading it this site is not responsible for privacy of the video. Another idea i have been thinking about is to impliment a shopping cart onto another section of this site. I already have a dedicated server and domain name registered with Lunarpages. This site is expected to have mass amounts of traffic and needs to be coded that way. This site is going to be an adult site, with adult content and adult videos, this needs to be implimented into the site properly for US laws and regulation on adult content sites so we are not held responsible if a juvenile acesses it.
