Need Someone That's Talented in Photoshop

Needing someone that is talented and completely fluent in photoshop to create a simple affect on the human body that is very suttle, but not overly done to where it looks purposely "photoshoped" (if that makes sense). It needs to have an absolute look of realism to it. Then, once finished, if you could provide written instruction on how you did it, it would be greatly appreciated as this is part of the project too. I will go into what I need photoshoped once the job has been accepted. Thank you.
