How do I get started?

Hey, y'all, I am 34 1/2 weeks pregnant and another ER nurse recently mentioned to me the field of consulting. My knowledge of it is scant, but I know I am not looking to get rich off it; I'd also like to keep my foot in the door of the ER.
This pregnancy is becoming more difficult and I wonder if any of you out there have any advice for getting started. I've looked at all the Vicki Mizzano (sp?) stuff and I think I am not interested in going quite that whole hog. Just a decent supplement of my regular (PRN) ER income so I don't have to spend all my time away from my new baby.
Any helpful hints or points in the right direction would be so appreciated. I am in Memphis, Tennessee, BTW.
Thanks!
