I am 27 years old and going back to school?

I went to college when I was 19-21 years old and recieved enough credits for an associate in applied arts and sciences. I want to go back now and finish that degree out as a bacholers in phys ed so I can be a PE teacher. I am single, work two jobs, and own my home. Would I be able to get financial assistance and would two years more of school be all I need to do this?
