Funny--which part of South Florida--what I've heard is that nobody in the wealthy northern suburbs of Miami up to Palm Springs takes insurance. And even then you still can't find anyone.
If you want insurance, there are several steps. 1) You need a receptionist to take billing info, scheduling, etc. 2) You need to contract a biller. 3) You probably need a separate contracted service for dealing with claim rejections, etc. I would expect the set up time is about 6 months or so, so you'll also need a business loan... it's very complicated.
