Well I'm opening a business this spring. Currently fixing up a old two car garage, the doors are 9x7 and need replacing the cost is $400. I don't know of any vehicles other than semi's that stand 7 ft tall and up so door wise I'm set. Also have to put in a drain for hand washing cars and paint outside of building, replace interior walls with drywall and run electricity to building. It's a good thing, I know a little about all fields, otherwise the repair bill would be astronomical .. (TOTAL) cost to fix up old garage I'm thinking ...$1000 thinking of car detailing shop name any Idea's?
