you should look at some schools with no loan financial policies. Off hand I know stanford, vanderbilt, and almost all of the ivies have it. You will get a free ride or close to one just from financial aid at those schools, you might have to do a bit of work study, but you won't have to take out any loans and the parental contribution would be very small or nonexistent. This site talks about schools with no loan financial aid policies:

Some of them are only no loan if you are below a certain income level. But it looks like you would be anyway. You should be in great shape to get a full ride or close to one from of these schools just in financial aid.
