Thats a big-ass heavy lift
They will need to load it on a trailer.
At your end you will need to make sure the concrete floor is thick enough and it fits under the ceiling.
Then you will need to install the floor bolts. Drill/epoxy?
Then lift it one piece at a time,position and bolt down
Run the Electrical
Install the ramps.
If it is a hydraulic seal leaking you will have to either replace it yourself or have the cylinder rebuilt. Or it may need a new pump?
And it should be inspected by someone that can see issues...refer to AA thread about car falling off lift.
Do you own a tractor? I would bet each ramp weighs close to 1000lbs
Forklift rental is @350 a day and 150 delivery...
Personally there are better alternatives... IMHO.
This may fit the Bill, Bill. 1300$
