As far as moving it around once you get it home, get 3 pieces of metal pipe 1/2-3/4" and about as wide or a little wider than the object you are moving. You can use galvanized, black or even solid round stock. Basically whatever you can find cheap will work.
Use a lever (long 2x4, piece of angle iron, Johnson bar, etc) with a couple of pieces of wood stacked on top of each other for a pivot point. Have one piece of pipe on the floor in front of the box. Lever under the hinge enough to slip the pipe under the front. Push it a little from the back so it starts to roll up onto the pipe. Let it get almost to the center and insert second pipe under front.
Now you're rolling. When the center piece gets to the back end, the front piece should be near the center so it's time to insert pipe 3 under front. Rinse and repeat until you get it where you want it. Then roll as close to in place as you want it and roll it off your pipes into place.
Getting it home is a different story and depends on if you have a truck or trailer and a way to unload it.
