You might check this school out:
Undergraduate Catalog
American Military University (You don't have to be military though lol.). The courses are only 250.00 per credit hour and books/supplies are included. They are regionally accredited and let you take a few classes to transfer elsewhere if you need to. I am planning on taking my language classes there since my current school does not offer what I want. Check them out and see if they offer the classes you need.
