Steel Building Questions

I am seeking bids from steel building people to bid my project. Has anybody had a large building done ?? Who did it?? Were you happy?
24x40,no regrets, survived 2 direct hits from hurricanes with only cosmetic damage. Not fancy looking, but does exactly what I need it to do.
Mike, American Steel Buildings are a good deal. Also Freedom Steel has some killer prices. Look em up on the net or I have the number for both places. I've been working on getting on of these as my next HOME for about a year. Mine's gonna be around a 100X150, 18 foot sidewall with a 4/12 roof pitch. So far I'm at $94,500. Still working on them to throw in the erection costs. ;)
