In my lovely little Orlando area, there are a few companies that still do 911.
Rural Metro still runs some 911 calls. Some. But they're also about to die in central florida and pull out. American is kicking their butt in IFT calls.
Health Central is a hospital based EMS 911 response, it covers some theme parks plus some of Ocoee. They're actually currently hiring for EMTs (I want that job! Arrgh!)
Reedy Creek EMS is in Disney, which is kinda "911 response" and you get the little golf cart ambulances. Who wouldn't want that?
EVAC is in Daytona Beach, they still do 911 response (last I heard. But I also heard they suck as much as Rural Metro does.)
Lake Sumter EMS
Polk County EMS (Actually requires you to be a resident in Polk County.)
Lee County EMS.
Orange County FD is hiring NON FD Medics for roaming Medic trucks. 12 hour shifts. They do require you to become FD within a certain time, but they pay for it. You must also pass the same fitness test their FF do.
There is still SOME job ops for Non Fire EMS out there, but they don't pay very well and they're kind of hard to secure.
