Hey there.
I'll let you use a little games character called Hank that I made for a Uni project (he's the guy in my avatar). The skinnings not absolutely brilliant, as he is a low-res character and I just skinned him for my needs, but he should be ok for what you want of him. I'll send a file of him to the e-mail address you supplied - he's done in Maya 5, hope thats ok.
Good luck with the paper,
