will the truck have a pallet jack? if so, you could have a flatbed tow truck line up to the back of the delivery truck, load the pallet onto 4 furniture dollies strapped to the pallet, roll it onto the flatbed, have the driver attach his winch to the pallet and roll it down the flatbed. then get the delivery guy, tow truck driver and a neighbor to help tip it up and carry it inside. I'm sure they would be glad to help just to see your work so far and to hear your plans.
