Hi Water Bandit,
One excellent source in Indiana is Rose-Hulman's homework hotline:
http://www.askrose.org/
It is a free tutoring service for grades 6 - 12 and I've heard excellent things about them. The tutors are generally very talented science and engineering students.
On a random note, I'm a junior in Engineering at Northwestern University and have tutored before. I am more than happy to help you out if you ever need anything. Best of luck this year!
