I hired a drywall company to do the framing (steel stud) and drywall.



Good decision. This type of work is really an artform. Yes a lot of people can "do drywall" but the pros can really make a difference so that you don't see seams and other imperfections.

Just out of curiosity, how tall from floor to ceiling? What are you going to use for floor coverings?
