Buying a kit building. Specifically Q huts

Be getting quotes for a 40x40 Quonset that’s almost 20’ to the center of the arch from the ground.
I am amazed, frustrated and starting to develop anger management issue after talking to so many salespeople that seem to think I’m an idiot. Prices for a kit range from $70k to start, but if I act today I can get one that’s on clearance for half that! Many more phone conversations later I have 2 written quotes for $23000 and change and $20300.
Both are comparable to the earlier $37k building. I have been educated about the inferior qualities of other companies, interrupted so many times that it’s hard to remember what my point was by the time I was “allowed” to speak again, pushed to the point of wanting to yank insulting sales directors through the air waves so we may have an up close talk and asked if I had an engineering degree. The response to the degree is I have over 30 years experience being handed designs by engineers and then building the project as I corrected the design flaws the engineers didn’t even think about.
I just wonder what type of experience other have had with this process?
As of today I’m going with either Curvco or American Steel Span. Both say they are factory direct but American Steel Spans office is next door to the factory based on the address given to me by Curvco for their factory in McKees Island PA.
Any and all comment are always welcome.

What I don't see in your post is what gauge the metal is for these buildings.

Are both quotes for the same gauge metal?

I no nothing about either company though I do understand the differences in guages of metal.

All quotes are for 18ga steel. AZ55 galvalume.

Just to throw another monkey wrench into the works. I had 2 other companies call about building from a lead generator form I had filled out.
These are both gable iron frame buildings. One company seemed very helpful and willing to work with me and for a regular gable end building 35x60 with 16’ eaves he came back with $35000. This eliminates working 10’ in the air to erect the Quonset but gives me 20’ at one end to build a 2 story apartment. Straight walls are easier to deal with. My plans are not set in concrete yet so I have the flexibility to change my mind. Quonset on top of containers is a cool concept full of unknowns until I start building. Initially I came up with the idea because when I tried to price a red iron building they were out of sight. I was quoted $85000 for the same building I have now, 30x40x14, that I paid $24000 in 2011.

Right after my last post I broke down and ordered a 40x60 Q hut kit. Almost 20’ center height. 18ga steel. I’m back in Wyoming now but my place in Alabama hasn’t sold so funds are tighter than I’d like. Also getting help out here for the things I can’t do myself is troublesome.
Since my concern right now is a place to live if and when Alabama property sells I am buy a prebuilt small log cabin that I can set up now and use as a temp house and then move to the river side and use as a guest house later.
Taking a risk on the Q hut as far as delivery goes but to pay the $25000 balance for a structure to sit on the ground over winter till I can get concrete poured and help erecting seems more foolish. I have 10 months by the terms of the contract to take delivery and the salesman said they would store it for a fee after that. Guess we’re going to see how all that works out but contractors here are telling me next summer minimum if I contract with them now.
In the meantime guess I’m going to be playing Grizzly Adam’s in a dry cabin while I try to get utilities and a well set up. Or I can pull water off the irrigation canal?
At least I’m moving forward!

Cabin was set yesterday and is almost chinked.
Think this was a good decision.
