Here are some FAQ in NJ.

http://www.state.nj.us/njded/educators/credentials.htmWhen I earned my credential, I was a sub during the day and took the classes at night. I went to Chapman University. They have a program that is meant to allow the average working person to transition into teaching by having the classes at night. Chapman is a one year program. Chapman has satellite campuses all over the US, so you could look into them. I'd also suggest looking at your local state colleges for similar programs. In CA, several years ago, you could be hired full-time if you were in a program earning your credential. Then, when it came time to student teach, you would do so in your own classroom. I don't know if NCLB (No Child Left Behind... you'll learn to hate these four letters... NCLB) allows this any longer. It also may vary from state to state.
I am in California. Our DOE is a mess. I have had to resend my application for my 5 year renewal three times now because they keep making errors (losing pieces, not posting after six months... things beyond my control.) My advice, be very mindful of deadlines and what documentation is needed. Get everything in writing and the names of everyone you speak to. There is so much mindless paperwork, it will make you crazy.
I also have a MA and am dreaming of getting out of the K-12 game and moving to adults. Community College is something I would love to teach.
For the purposes of full disclosure, I am leaning very strongly toward making a career change and leaving K-12 teaching. Best of luck to you. Feel free to respond here or PM me with any questions. I'll help you as much as possible.
