FlightSafety in Vero. Not exactly Central Florida, but still close. I worked there ten years ago and trained CFI applicants. I recall that FSI has a way with student benefits and should be able to set you up.
I don't know anything about Comair. Look into ERAU in Daytona. I work there. I also work with a couple of guys who came from Comair and were happy to be out of there. If you have any more specific questions I can try to answer them for you.
