Loans for school?! Please help!?

I'll be a sopre in college next year and I'll be transferring to a pretty expensive university. Costs add up to about $30,000 a year. I applied for several loans this year and I kept getting rejected. I found out the reason I was getting rejected was because my co-signer (who happens to be my mom) has TERRIBLE credit. Does anyone know any loans where you don't need a co-signer, or perhaps a loan company that tolerates bad credit. I'm in desperate need of money before school starts in september. Can someone tell me some good loan places to apply to?
