Angel,
If you have a place that you are moving into down in Florida when you arrive, I would suggest PODS. We used it to move our entire house from Michigan to Houston. Lonna towed a 6x12 enclosed trailer behind her SUV with basically all my garage in it. I had a Caprice station wagon that was loaded with odds and ends and I towed the trailer with my bike at the time on it.
It's not super cheap, but it was cheaper that renting a uhaul truck, getting a 3rd person to drive it and then fly them back to Michigan, and the fuel to get it here. The only other option is rent the truck put the trailer and bike on the back of your van. Wish I had some better advise, but there is not real cheap way out of it unfortunately :-/
