Help needed for my Tutorial

[nithinks]

I am planning to write one more video tutorial. For which I need Two video clips(10sec each).

First, A person sitting on left corner of sofa with dark colored shirt and pant.

And Second, Same person sitting on the right side of that sofa with dark colored shirt and pant (different color). Note that sofa must be fully covered by white cloth and no color, other then white must be visible in the video clip
Please turn on all the lights of that room,and dont change the camera position for two clips

Thanks in advance
