Not sure if you are still looking for a lift but the link below is what I ended up using to lift our 240 gallon tank. Basically a 450 LB material lift. If you know anyone who is in the IT field and their work has a server lift it would also do the trick.

Personally speaking the material lift did work although I didn't think it was the most safe way of doing it. My tank is built on plywood so all we did was lower the lift a tick below the shipping pallet and slide the tank onto the forks. Then raised it slowly a tick above the steel stand. Then slide it on. The more difficult part will be to move it into the house but the plan is to build a temporary stand out of 2x4's (mostly salvaged from shipping crate) and use a set of 500 LB casters I purchased.
This way I can just slide it onto that and move it into the house. At least that is the idea...we'll see.
