Need scary zombie arms illistration

I need arms drawn for a game I'm working on. They need to be outstretched, as if reaching for a victim. They are to be drawn from the point of view of the zombie itself. In the end they're going to be used as if the player is looking through the eyes of a zombie, about to catch it's prey. Photo-realism is a bonus. They need to be in color. It's important that these aren't 'cheesy'. I'm going for scary, bloody & gory. I'm picturing them with (very little) tattered clothing, and lots of rotten flesh (a greenish grey color) showing. The fingers are are outstretched, grasping for it's prey. They need to fit in a 640x480 screen, but in a way as not not obstruct the view, provided is a file with an approximate position & size that they need to be in. I need these right away. Thank you! My budget is $30-$35 for exclusive rights to the illustrations.
