You can try Greyhound bus lines.  They can move crazy stuff, for not so expensive.
Or if you work at or know of a business that uses regular truck freight (Fedex Freight or Old Dominion, etc), then ask if you can use their discount to ship it.  You would have to put it on a pallet and strap it down to be moved with a forklift.
UPS and Fedex won't ship something like that.  It's too big.
