Kyle,
Three years ago I had T-N-T in NC (there is one in Maine) build me a metal building with an open lean to. The building is 26'x22' and the lean to adds 12'. It is 12' high at walls and 14' or 16' foot at center. I have two garage doors and one side regular door. It has a 20 year 120 MPH warranty. It was $7,200 installed.
I wanted a concrete floor (slightly over 26'x34') and it cost $3,200. I had to have the base of sand and the removal of dirt, adding sand and a gravel entrance (90'x35') added $1800 for a total of $12,200. I then added a 14kw Gen, propane tank and fully wired the building for $14,000 more thus $28,200.
Not sure any of what I list helps, but thought it might also show the prices can be had for a lot less. Hang in their and you will get the price down. Heck..for that quote the Amish would move to Maine to do the work!
Best to you.
