Our local fish shop provides this service (moving) and there are others like moving outfits which will due it for a fee. Buying a tank that large on line has a good chance of getting broke by the shipper. I spent 20yrs working in the trucking industry and they would be handling that large of a tank with a fork lift. They pack everything high and tight and would probably stand it on end and jam stuff around it.
IMHO you would be better off to buy local and make moving it part of the deal. Good luck...
