After Effects expert to do a small roto brush job

PLEASE READ ALL BEFORE APPLYING Hi there. we have a video where we want to roto brush out a running girl. its only about 5 seconds or so. I will send you the video in high rez and you need to send it back to us inside a after effects file. You have to separate the running girl in one layer ( just the girl) and the background in another layer. In the middle layer you will just have to add the render of an image we made using 3D studio max. this image is a PSD and if you can please make the image match the tone of the background so that it looks real. here is a video of the technique we want to use.

We are hoping to get it ASAP. Thank you
