We are not all that far from you and went through the same debate when I bought my property, which was not a farm at all, just a big chunk of acres with a house.
Oh the choices... metal ones, wood ones, kits, prefabs, scratch, roofing types, not to mention styles. Oh yeah... the budget too.
There are a number of barn builders in my area and I went with an Amish company that allowed me to place an order for my barn based on one of their somewhat pre-fab designs with my own modifications added to it. Now I didn't have horses at that time but got an all purpose barn with a large over hang, horsie style
Most of the major ground grading I did my self with my tractor and they finished it to their specs then laid the base. About three weeks after I placed the order the crew of about a dozen Amish workers showed up along with the materials and I had a barn put up lickity split.
Having built a number of smaller pole buildings and storage type stuff I knew my capabilities to build the barn I wanted did not match up.
I love my barn and am glad the experts did it and I did not try to build it myself. A friend and neighbor farm has an all purpose pole barn they built themselves. They did not grade it right nor build it as well as a professional. Initially it wasn't bad and got them by, but the barn is less than ten years old and every year they spend considerable amounts of time and money fixing it.
Everything needs fixing... the base, the floors (rotted out) the frame the roof, and especially the grading because it floods something terrible. It shouldn't considering the placement and the gaps and holes it developed are alarming.
Anyway, just my $0.02 worth.
