Realistic Photoshop Head Swap

I'm looking for a talented Photoshop expert to help me swap a head onto a body in a realistic manner. There are 6 photos that I need to have done.This image needs to look as authentic as possible. This is also my first time using Freelancer.

Please let me know if you are interested in the job, I don’t think it is a huge job that will take a long time, but then again I know very little about photoshop. I would pay $20 a photo, so $120 in total.
