Structures like this one are one of the easiest buildings to take down and rebuild. Inside the roof are steel ladder trusses. Although It's pretty big, a small crane or tractor can easily handle the heaviest items.
These commercial structures are almost always disposed of due to economic forces and not because there is anything wrong structurally. Hazardous waste companies often need to clear stuff like this away to make room for re-development and environmental clean-up.
Expect to get it free if you remove it or around $3000 - $5000 stacked on a trailer.
No building system I know of gives such a quick roof. Once It's up you can fiddle away building walls out of whatever without the worry of snow and rain problems.
Every city has contractors capable of transplanting these. For most of us,that's the best option. With a sturdy roof overhead, the project can proceed at a comfortable pace.
