Junkman,
The building that I described was $5500 plus sales tax delivered, and the 12X12 roll up door was about $800, and the steel walk in door was about $300, with hinges and lockset. I purchased the doors locally and installed them myself. The concrete slab was $3200, complete, but I had to have the ground level, so that cost me a few hundred bucks. I had a few friends come on a Saturday and we put up 6 two foot arches the first day. The arches are assembles on the ground with bolts, and then swung up in place and then are attached with the other arches with bolts, and are left finger tight untill the complete building is erected. There were four of us the second day, and put the arches up one piece at a time, and at the end of the second day there were ten arches in place. My dad and I then finished in the next 5 days. ( 5000 Bolts & Nuts shipped with the building, and also included the base plate that was bolted to the slab, with 5 inch wedge anchor bolts, 116 of them, the anchor bolts didn't come with the building) I also put plumbing in for a bathroom, and 2 four inch PVC pipes in slab to bring in water pipes, and electricity from underground.
Was a fun project.
