Have her check into the scholarships & loans offered by Delta Gamma. I'm not certain if pledges are eligible, but I had a $500 DG loan my senior year to pay my dues & fees. Back then (27 years ago, eek!) they were very easy to get if you could show reasonable need. Here is the link with the loan information:

I hope this helps and best of luck to her!
