Alas, I don't have any direct experience with what you're dealing with, but I did want to suggest that you might want to start with doing some temporary jobs.
Folks I know in the bookkeeping world have used Accounttemps (do they still exist?) but most temp agencies have openings for bookkeepers and accountants, and there never seemed to be a shortage of jobs. Working as a temp would give you a chance to get some experience under your belt and learn what skills you need to move up.
And you never know - it might just lead to a permanent job (it happens a lot!).
Good luck!
