Dunhams was the same with expen$ive outside service that would have also charged mileage. So they loaded it in my truck on it's side, when I got home we slide it on it's side down wood ramps and in thru the front door where it was then tipped upright onto the largest furniture sliders to be found and slid it all the way thru the house across 32" X 48" pieces of masonite aka hardboard atop the carpet. It ended up being much easier than expected.

From a guy that built people elevators for better than 20 years, change those pvc rollers to wood rollers. 3' wood dowels or broomsticks....
Wood doesn't collapse or shatter and when plastic fails most likely fingers will be under the safe.... The fingers you save may be your own.
If you are going to use rollers get at least three, two under the safe and one starting under in the direction the safe is being moved.
I use several 1 inch thick pvc pipe rollers and some flat pieces of steel. Moved the safe easily, just take up the sections behind and put them in front. One of the reasons I keep the safes anchored is because I'm certain thieves know how to do this as well.
