If it's crap ... We'll tell you
if you're desparate for money, you could try this:
I went through art school for a few years and had some mixed feelings about nude modeling. I guess first we have to know, how big is you school? And are you an art major?
I only ask these questions because if you aren't an art major, and at a big school, you will rarely run into someone that you have posed for. When I was in life drawing, half the models were art majors, which was extremely awkward. You'd be in a painting class with them in the morining, then your next class they show up in a bath robe. The money is excellent though, and the work is pretty damn easy for the most part.
Make sure you don't do comic book poses, or even worse fighting game poses, everyone will just laugh at you. Had a fat model do a hydouken pose and had to leave the room before I started laughing hysterically.
Also be aware that they probably be posting some of these drawings in the hallways, so your private bits will be full on display for people that you haven't even posed for. But if it's anything like my old school, the art department was all housed in one single building which only art students went to.
After you wiegh all of this, again remember that you are getting paid $100 for just sitting, or standing there. If you can get past the awkwardness, it is very much worth the cash.
$100 to sit around naked for an hour or so.
Do it and don't give a fuck.
Pick up some hot art chicks while you are at it.
