One option, go get it, roughly 1200 miles one way. Make a week of it, see some of America on the way. 2nd option, contact a U-Ship contractor and get an estimate. Most will load onto another trailer, less expensive folks would pull trailer directly. Similar in scope, hire someone to get it, college is out right now, surely you could locate a starving college kid to go get it? Third option, call a trucking firm. It would require boat owner to figure out how to get it to a shipping dock I would imagine. Personally, I'm an option one guy all the way, love the adventure.
In fine running order with the 2.5 OB, I would estimate a value around 6500-8000, so at $2200, you have lots of wiggle room.
