I have to say finance is one work related area I would seriously not want to be working in full time.
I guess the only saving grace if you work in a finance office is there might be some hot young admin girls to stare at
Each to their own but to switch industries now without any experience might be tough, especially in the current climate. I switched industries at 27 but it was from one management role to another so it wasnt too much of a hardship.
Good luck
