I doubt you will find a moving company that will do it for any decent amount of money. Any pro company will want to crate the tank up. Best bet is a bud with a pickup (as suggested), or a couple friends and a U-Haul rental.
Getting it in the truck is no problem. I have a work table on casters and can role it right up to the truck. I off loaded it by myself the night of the frag swap.
