I used to manage a Ferrari/Porsche dealer in FL, and acutally rather than just getting one, you may want to either use a broker, or get a number of quotes. One of the most reputable is called exotic car transports, but there are dozens in the area that are all pretty good. If you go on the website for the Dupont registry, I think they have a listing for different car carriers, that would be a good place to start.
Let me know if you can't find anything and perhaps I can help. Keep in mind it's gonna cost you over a grand to do it enclosed this time of year.
Later,
