The only experience we had was quoting with them. We quoted with Morton, an Amish guy and a local contractor. Morton was thousands more and the Amish guy was several hundred more than the contractor. We did a very basic building with no electricity and it still has a dirt floor. Basically it's just a huge shed to store the tractor and Airstreams in. It sounds like you're looking for something a lot more complicated than the one we have.
