Mike - I put up a 30' x 40' x 10' metal building fully insulated, one walk in door, two 10' x 10' roll up doors (one each end), 3 windows, 2' overhang all around, 4-12 pitch (standard was 1-12), and guttering. I priced it at Morton first. They quoted something like $26K. I went to Mueller. Their basic prefab bolt up kit was about $5500. With all the options I chose (noted above) the kit was about $9500 I had a concrete contractor build a slab with extra steel and concrete for $6500. That put the total about $16K. I plumbed it myself and built in a bathroom complete with shower. All that plus a litte more and I was still below $20K.
If you are so inclined, Mueller is a good do it yourself project. Takes a lot of hours, but feels great when you finish. Or they can put you in touch with local contractors that will put it up for you. They have lots of standard sizes available. Check their web site. And they are local.
