Do you what to be an owner or just drive a fleet owner's truck?
I personally don't know any expediter companies based in Florida. My list of worthy companies to lease on to is pretty short though. Landstar is based out of Jacksonville, FL but their orientation is in Indianapolis.
Word of advice, if you can't afford to go to another state for orientation, I don't believe you are ready for being and owner operator in expediting. I'm not telling you what to do, but I've seen plenty go out of business because they were under capitalized. At a minimum, you should have 6 months of expenses saved up to weather the slow times and those unexpected repairs.
