It's gonna be more expensive, because it's a specialty item.
That show on Cable where they bid on transport jobs would probably do it:)
They had one guy move the Grayhound Bus Conversion that a member of this forum bought, so I'm sure that they could move your trailer.....but probably not cheap.
Another option might be to contact someone via Craigslist, to see if anyone is traveling down to Florida without a trailer, but has the TV that would handle it. Then, pay for them to tow it down....plus something extra. But, you would be taking a risk doing this, unless you know the person.
