I'd like to make a suggestion.
Next time you put out a question, make it a real one. With details.
The steel can be as thick as you want, price will as well.
Those windows and doors can be anything, including the big ones.
Gonna put it on a foundation? Where? Insulated could mean the
skimpy pink foam that gets used under vinyl siding.

If all you look for is the total enclosed volume, the estimate will
either be quite low, or some companies won't even want to deal
with you because they know you haven't thought it through enough
to be getting functional bids.

Just my opinion, worth what you paid.

Good luck, I went through this a couple of years ago, when I considered
installing a steel Quonset building. I really wanted to compare products
and prices over the net, but found it was difficult to get anywhere near
accurate pricing via the automatic estimators and every company I
contacted came off like shysters. They all have "special deals" on units
from cancellations and all manner of hustle tactics. It just seemed so
seedy I gave up

I have run into this already. Seems like there are so many "cancellations"
that people want to blow out. There seems to be some long sad story
attached to every building.
