After Effects - Rotoscoping - Roto Brush - Background Removal

I have a series of video interviews recorded in HD. These were filmed at an exhibition with the clients branding visible in the background. The client has now re-branded and would like to update the videos. I need a range of interviews rotoscoping. This job is for Internet streaming video only and not broadcast, however I need a professional quality rotoscope. If I had more time I would do this myself using After Effects and the Roto brush Tool. (Please bear in mid when quoting that i know how to do this and how to use roto brush.. if you don't, then don't apply) The final videos will be rendered out with a new jpg background, provided by me and uploaded to youtube by the winning bidder. I will also require a cop of the AE project. There are about 8 or 10 videos in total all of different durations - Please quote based on the first video with a duration of 6 min 30 sec. ~See attached jpg for example of the actual video framing - the top shot it the one that needs rotoscoping. All videos are just simple head shot interviews locked off on a static tripod shot. (no cut aways or panning)
