Hi Tim,
I'm in Tallahassee, so not that far. Shipping wouldn't be terrible, it can ship UPS. Right now it is in one large piece (2" thick X 66.5" long) plus various other smaller pieces, some aren't suitable for a platform as they are leftover strips and thin pieces from what I ripped down when building my platform. The large piece is enough to do another for an 18' Skier but I don't know about the Advance or anything larger than 18'. They may be wider than the original 18' Skier. Attached is a pic of what I have. It cost me $600 and I used half of it. So I'd be looking for about $300 plus shipping. As a guess I'd say probably $80 range to ship, but I could find out from FedEx if you send me your zip. It is very nice marine teak that I got from Florida Teak in West Palm. Here's a pic of what I have.
