Vick, I'm not sure what to tell ya on how to get started. If you have no experience in this field...I'd say you need to find a contractor in you area that is doing this type of work and see if he will hire you. It's a tough business. Without someone to show you the ropes...you're going to make a lot of mistakes.
If you're dead set on making it without a mentor. Then apply to as many nationals, regionals, or local real estate agents as you feel comfortable with, and buckle your chin strap...it's a bumpy ride.
Also, set your own parameters. Do only work you are qualified to complete, at a price level, at which, you feel you can survive.
