How do you ship large items? Help

Yeah, I want to buy these very large speakers from someone in Audiogon, but he does not have the boxes or crate that they were shipped in. I talked to UPS frieght and they told me that large, heavy items must be on a pallet, secured and wrapped before they would accept it. How would i go about finding a pallet and then securing it to the pallet and wrapping? Is there such a service that will professionaly pack items like this? Ive never had to deal with something like this so im totally lost here. The speakers weigh 250lbs each and are over 60 inches high. I quess i could drive there myself, but its 1100 miles away!!
Not your average day trip ya know? Any help would be appreciated here. If i can't find a solution i just won't be able to buy them, but it is a good deal! Thanks all!
