I have also been flying air ambulance out of the Fort Lauderdale area for almost 5 years now. I know a couple of companies will take someone with a good attitude and willingness to learn and be a team player over someone with a lot of hours. The reason for that being that the work is very demanding and the schedule is rough. During our busy season, which is in the winter, we pretty much fly around the clock. And like its been said already, most of it is at night.
I know that there are at least 2 companies that will be looking to hire in the near future, if not now. There is starting to be a lot of movement out into the airlines, especially the FO's.
