So here is my suggestion (another option), try visiting churches and social organizations around your area. At times if you are lucky, may be your can find a generous donor or may be someone willing to co-sign your loan. Sometimes they do have funds allocated to help in such situation. A friend of mine had their loan co-signed by their host parents. When I struggled financially, after all attempts I directly made an appointment with the vice chancellor of my college (it's a pretty big college with 10,000+ students) and bugged him for financial assistance. It worked. I was able to get an additional $2000 on student scholarship...

Hopefully this helps.
