Pam,
Financial aid for college will give you enough money to buy a computer and pay for classes. The FRAG in florida gives a student about 2,500 per year. This is enough to pay for tuition, books, and a computer.
(I'm going by old numbers. The stupid folks at the state capital might have cut the budget a little but I don't think so.)
Keep your eye on Free cycle. Here's a sample of computers being rebuilt in New Mexico.

Yeah. I know that random links are not helpful.
I'm saying that you can search, make phone calls, and ask.
So here is my list to think about
1. computer and other companies, 2. non-profits, 3. us, state, and local govs.
