Other ways to pay for college?

I'm a college sopre and have been paying for college out-of-pocket. I haven't been able to take out student loans because I have no co-signer since my father and brother have been sick and my parents credit isn't capable. I also got almost zero financial aid because on paper it seems as though my parents make a lot of money. I'm finding it harder and harder to pay for college and don't know how to go about scholarships, etc. Please help!
