Rent a hydraulic or manual gear lift if it'll fit through your door - just remember to counterbalance.

If all else fails, call a moving company and tell them you want to move a glass tank 20 feet and 3 feet up, they'll probably rip you off and charge $400 but they'll do it.

If I could go back, I'd probably rent an electric forklift.
