If you can get a forklift in to move the machine hiring an equipment mover might be the way to go. I received a quote recently to move a 2400lb lathe. 200 dollars
The seller would not allow me to move it myself inside his shop (commercial operation). The mover was coming from 20 miles away and placing it onto my equipment trailer. Well worth 200 dollars
If you can't lift the weight back at your shop dis-assemble the machine.
Call surplus equipment dealers. They may also have a better deal on a machine for you. Prices are real low at the moment on quality machines.
