I work as an admissions officer for a private school and I know a little about financial aid......so I hope I can help.
First of all, do you know what type of loans she needed a co-signer for? There are some types of loans where you WANT the co-signer to be denied because that means more money for the child (I know, it sounds very confusing and ridiculous, but that is our lovely govt). So make sure she has checked on this. Has she called the financial aid department of the school to tell them this. If she explains the situation, they might be more than willing to help her out.
As the previous poster said, talk to her soccer coach, the one from highschool and the one for the college and see if they can recommend anything.
And hit the internet and look for scholarships and private funding. I know that the time is ticking, but it is worth a shot!
I hope these suggestions help. Let me know if you have any other questions!
