re: Metal Building Recommendations

We built one around 12 years ago. We got good a price from a steel truss company who had the building up in less than two days (some time between days for concrete work and curing). I saw the receipts a few weeks back when going through some paperwork, but can't recall the exact cost.
Fast forward 8 years, and we had gotten an Amish guy to build us a 12×32 portable building for a work area and storage. The guy does great work and beats most any portable building price. Our plan was to build a lean-to on one side of the building, partially closed in, for lawn mower storage and whatnot. I drew up what I wanted, and gave it to the folks who built our metal building. The quote they gave me was outrageous. I didn't even attempt to extrapolate out to what my metal building would cost. In just 8 years time, the cost skyrocketed, especially considering the size/scope of the build.
I bought some used trusses, and have most of what I need to build the lean-to, but haven't gotten around to it.
