Create an Animation

I have a 3D human scanned model (wavefront obj file with materials). The job is below. 1. Clean up the model and reduce the number of faces. 2. When the human model was scanned, she was wearing clothes. Modify the texture so that it would like she wears underwear. 3. Rig the 3D model in Maya. 4. Animate the model. The current model has T pose style. The first animation is to change her pose to more fashion model style pose. The transition from the T pose to the target pose should be smooth. I am looking for 3-4 target pose. Again the target poses should look something like fashion model poses in front of camera. 5. Once the pose animations are done. I need fashion model style walking motion. If possible, use the motion captured data so that the walking motion could look more realistic. 6. I need this in 2 days.
