Does anyone have advice about building a new pole barn on my property?

My 50 year old, 30’ by 40’ ( 1200 sq ft ~ 120 sq m ) pole barn was crushed by a massive tree about a week ago. The tree broke the main ridge beam and 5 out of 6 of the trusses. The tree has been removed and I managed to get almost everything out of the barn with only ~$2000 worth of damage to the contents. While it is still standing the building has been condemned and the insurance company has totaled it – meaning full replacement.
I now have to look into finding a replacement.
The barn had a concrete floor so the next structure will need to be larger about 2 ft larger in both directions 32’x42’ (135 sq m).
I will not do the work myself. I have contacted 2 companies: Morton and Hansen and one of them responded immediately with a custom kit.
Does anyone here have experience with such a structure? Do you have any tips or recommendations?
I really need to get this done before the snow!
