Hey Dog,
One thing you may want to look into, and see if anyone is still doing it... In some states, where they have a shortage of teachers, they have established "fast track" teacher certification. In Illinois, a few years ago, if you have a bachelor degree, you would interview with a school district that would take you on, and more or less "mentor" you through the program. You split your time between the school and going back to college for an accelerated course to satisfy your basic requirements. IIRC, Trinity College in Elgin was quoting 18 months to complete the program.
