It sounds like you are looking at working at a brokerage (like me).
The first thing you need is your level one license but I wouldn't worry about getting that BEFORE you start applying. Most offices will pay for the course once you are hired. Generally speaking the pay isn't all that great to start ($26,000 - $35,000 per year) as you will probably start as an assistant.
However, if you can hang in for a couple years, I've seen everything from the career salary staffer at $45,000 to a commision only broker into six figures.
I don't know if that's much help to you but if you have other questions just fire away.
