There are some "colleges" I think, not universities, where you can get local rates. You should check your local community centre, which might offer some that work toward what I assume would be the equivalent of an Associate's degree. I looked into it, and found I could get a teaching assistant diploma at a local rate, but a teaching degree had to come from a university, which was gonna cost 3 times as much unless I waited for the 3 years. The teaching assistant degree might be an option for you, as it would help you get classroom experience while you study for your teaching degree later on. Good luck!
