Extensive PhpFox script Modifications

We are in need of an EXPERT PHP programmer that can integrate ALL of the features of youtube seamlessly into our PHPFOX (version 1.0.8) social networking site... wildfun.com. The site currently resides on a dedicated server, so the person we want must be able to make any changes necessary on the server. The pages and functionality must blend in with our site seamlessly. We want members to be able to upload their own video, rate others video, forward links of their video and other members to friends to build more traffic to wildfun.com. The videos also should have "wildfun.com" displayed on them somewhere, so that anyone viewing the the video can "click" on it and visit our site. The member must also be able to place a caption/title above their video so they can give it a title and short description. The member should be able to upload different video formats that will play seamlessly to those that try to view it. If you have a database of videos that we can add to the site it would be a plus. We want an admin area (or add to the current admin area)where we can choose to allow only "members" to view the videos or allow "guests" to view the videos. We also want to be able to add our own videos, delete videos we feel are inappropriate etc. This is just a start for the site. In the near future want to be able to have work done on it as it grows, design changes, script modifications, adding more games to the game section etc. This is just the beginning. It would be nice to have this expert maintain and manage the site for us as it grows.
