Suggestions on building a garage in central Fl.

u.s. steel buildings did my shop roy,was 13,900 back on 2000 complete with concrete and permits etc.its 24 x 30 but larger wasnt that much more expensive.......wish I would have gotten a bigger building lol but it serves it's purpose

I was looking at a 30x40 from them. I inquired new years eve and they called me 52 times between then and the 13th. Very high preasure sales tactics.
