OK, this may be totally off the mark, but if you are just looking for a job to pay the bills while working on your writing, I'd say maybe think about becoming a flight attendant.

From what I understand, the work is relatively easy, especially if you like flying and can tolerate people. They train you, so no real experience required. It's not really a forever career for most people, but it's a job that pays decent and gives you plenty of time off. The schedules can be very flexible; you can work depending on how much you money you need, and you would have more free time during the week for writing. You'd also have time on overnights to write.

I have a sister in law who is one, and it really works for her, as far as time off. She works maybe three days a week max.
