[Project] 3D-Modeling

[JetRaiden]

So in Technology class today, my teacher caught me playing Ghost Recon. We were supposed to be working on a project, one kid is doing some shit on Unix, another is making a Doom level. I still hadn't decided what I was going to do, so when he asked what I was working on, I said it was my project (yea, Im clever). He says for a project I would make a character model for a Tom Clancy game. Not thinking properly, I said "sure...." So now I need to find a 3D-Modelling program (maybe a free trial of something), I need to have a skeleton and basic outline of the model by friday. I have no idea what I'm doing. Plz help.
