Think I am getting screwed

[Ryank]

I need to vent, I have taken ownership of a large sailboat, and had arranged with a Shipper out of Florida to pick the vessel up and deliver it. The shipper and I had agreed on a date next week (even confirmed it this past Monday) and I get a phone call today asking if the boat is ready as he is up there (1400 miles away) When I remind him of the conversations he acts like he had no clue, got irate and hung up. Now he wont return any calls and has a fairly good sized deposit. I am hoping he realizes he screwed up and fixes this but I am thinking I have been taken by someone with a good rep on several sites including THT. Short of blasting his reputation to Shreds all over the net and small claims court, not sure what else to do.
I did sign a Transport agreement but their is no date on it. I do believe I have an email somewhere with the original requested dates.
Any advice would be appreciated.
