Metal Buildings, best company to use, also wood construction ?s

I bumped my new shop build up to the top so might give you some ideas. I blocked up 3 blocks high and used regular 8 ft studs then had trusses built like a tray ceiling to give me an additional 2 feet in the center bay so I have plenty of clearance for 4 post lift when I get around to installing it. I also used spray foam insulation and am now installing pegboard. Just takes time when doing it myself,Joe
