What about a Perkins loan? See here:

Perkins money is lent out by the school. Basically, she should appeal her financial aid package, saying she needs more money and inquiring about a Perkins. Interest rate is 5% and it does not require a co-signer.
She should also keep looking for jobs. Sometimes students quit as the semester goes on and they realize they have less free time than they need/want.
