Adult Site Conversion

We are a young couple who run their own amateur adult site. We post video and photo content, use the CCBill processor for payments and Strongbox security system. We have a simple member's area and a free area with blog and punBB forum. Right now we have about 400 unpaid users who post into our blog and forum. We are using the BLOG:CMS 4.2.1c system and would like to convert our site into a more user-friendly open source CMS - in a LAMP environment. All blog and forum content would have to be converted plus the accounts and posts of all the users and members. Furthermore we would need some new system of video and photo content sorting and publishing since now we have just dedicated blog categories for videos and photos with no tags. We would also need a hosting solution that can take 3 TB of monthly traffic at a peak, with good speeds for downloading video. So we are looking for someone who would make us a completely new site (we purchased even a new domain) based on the content we already have and preferably would have some experience with adult websites and CCBill processor. Good design skills and flash programming skills might be an advantage.
