Photoshop Image Request, please help!

[sonyblade]

i really need some photoshop help!
i have three images that i need to combine. I don't know how difficult this would be, but i hope its not too difficult for someone to help me out.
i need someone's face on someone elses body, and not a too complicated tattoo put on the body.
if youre interested in helping me out (please please please!)
i want the face of the guy on the man in the green shirt's body. i have access to different body shots and more images of the face if you need them. then, i need this specific tattoo placed on the ribs under the pectoral (in the general region that it is in the picture)
i really need this to be as seamless as possible! i would greatly appreciate it

Hey! yeah that would be great, if you could make a couple of changes? if you could downsize his nipple and maybe downsize the tattoo? i was hoping to get the tattoo the same size ratio to the body as it is in the Tat Pic.
i don't know if what im asking is too difficult or not but i really REALLY appreciate you taking the time to do it PhotoshopTroller- thank you!
remember, if it would be easier if you had a different body to work with or a different face to work with - let me know!
