Depends: What work needs to be done?
We are finishing up our remodel and had to: turn a slope floor to flat (66 feet by 18 feet)for a new hallway, bathrooms, and put in a second floor for a new booth. We hired people to do: the plumbing, concrete floor cutting, block wall cutting, carpet laying and raising sprinkler heads. We have been doing all other work ourselves (framing, electrical, sheetrock, etc.)
I expect we will have $20,000 into this not including equipment. Lost of variables can effect you cost.
