There are a huge amount of private scholarships available as well as financial aid at certain universities. Unfortunately, trying to figure out which scholarships to apply for can be very overwhelming. I am not an expert but would recommend a few things.
1) Start doing some research online on where to find scholarships and how they work...perhaps starting with a few listed in this article http://college.usatoday.com/2012/01/30/the-10-best-sites-to-look-for-scholarships/
2) Find a few colleges that you are interested in attending and ask them about scholarship and financial aid information
Just remember that it may seem like information overload at first, but the research and time spent applying for scholarships could save you a lot of money in the future.
