Well to get it up the 4 steps I would put plywood down over the steps to make a ramp...getting the tank out of the truck will probably need to be manpower 10 guys as they have suggested. get it out of the truck and onto two or three piano dollys then push it to the ramp you've built and get your 10 guys to push it up the ramp and into the house.... I had a 7ft x 20x24" tank delivered in a crate to the driveway....I got acrylic because it was supposed to be lighter than glass...figuring my daughter and I could carry it...NO WAY POSSIBLE. I called a guy who had an add in a small paper saying he removes things anything from the basement, attic, garage, etc. I called him up and asked if he could maybe just once do the reverse and put something IN the house. he came with 4 guys and for $60 put the tank in the house for me!!!! I hate to suggest this, but if it is really heavy maybe a funeral parlor will rent you a casket lifting gizmo. these things lift concrete boxes, so they should be able to lift a tank.
