You are blessed with your contractor. The building looks great!
I did my homework before picking a contractor. A lot of companies wanted to sell a pole barn package.
Looked at Morton Buildings, Olympia General Steel and many others but found most the advertising we see for pole barns is for the material only. Most these places will put together a package for the style and structure, include hardware, siding, etc., and drop ship it to your property.
I found out after speaking with several companies, when the orders are shipped, you might not receive everything because of the tariffs. Some items could be on backorder.
In addition, if I would've taken that route, I'd need to find a contractor to build it, then a concrete company if the builder couldn't arrange it.
Finding all these separate companies might be an ideal way to go if you know who to use in the area, and if you're there to oversee everything. Essentially, you'd become the contractor and sub the job out to everyone else. This wouldn't have worked for me, being 9 hours away. When I found all this out, I decided to go a different route.
The company I used took care of everything. They had their own building crew, mostly Mennonites local to the area, and did all the ordering of materials. They also have a sister company that exclusively does their concrete work.
It just seemed the best way to go.
They broke ground on October 22nd. So, roughly 2 months from start to 99% finished today.
