Before stumbling across my current location ( an American Steel building going on 24 years old) I did some research and narrowed my choices down to the following few companies:

http://www.conestogabuildings.com/
http://www.freedomsteel.com/
http://www.olympiabuildings.com/


All have a great reputation and will custom tailor to your wants and needs..
