I don't have a specific recommendation, but since you're in Florida you might check with boat haulers (check local marinas for suggestions).
I've twice had a 36' boat moved several hundred miles. They loaded it up the flatbed of a semi and off we went (OK, it took two days to get it ready, but you've got the idea).
These guys are accustomed to hauling big loads and have the necessary insurance. Pulling a 5th wheel would likely be like a day off for them.
