best route to get into nursing with a masters??

I currently have a Bachelors and Masters degree in Accounting, and work as an auditor. I really do not think I can hack it forever, I have had 7 different jobs in the past 3 years. Nursing sounds exciting, but how do I get into it? BSN? PA? All these other tags that they have? I would like to do the least school, I realize, but I have a kid and need money as I am the only source of income. Does anyone have any suggestions?
