Dennis, this may be self evident, but you'll need to get it bolted to a sturdy pallet. At a minimum, build a frame around it with dimensional lumber. If you want to go whole-hog, enclose it in plywood or OSB. Your pallet needs to be where the driver can get to it with a pallet jack and into his truck without any steps or steep grades.
Be sure to insure it. When you use brokers, which is what most of the online services are, there are often three trucking companies involved. Company A does the local pick up and takes it to the terminal. Company B does the long-haul. Company C does the delivery. If there is damage, the other guy did it. That's when your insurance is important.
