video database with playlists

Create a video on demand library that enables users to do more than watch video streams, ie chat rate files. A key function is the ability match the users profile with the profile of the video file. A second key element is the ability to create and watch/ send windows media playlists, together with the ability to add advertsising pre and post clip. I envisage 5 relational databases in total. Prefer to work with people that have good tech teams for fast delivery, long term relationship together with latest skills ie ajax etc I will send more details to candidates i select
