anybody have any experience with putting up a metal building? you know the kind where you can buy the material in kit form and build it yourself. i have GOT to do something to free up my garage. looked at having a shop stick built but both estimates came in at about $18 sq ft and this was just dried in. i think i can buy the metal building for less $$ but not sure about constructing it. would like to have a 30x36. did a search but didn't find anything specific. if you have any knowledge on this, please share.
