My husband took on a big drywall job for his experience. He typically has only done small drywall repair jobs and also drywalled our addition (which he completely built himself) and he does a great job. Anyway, either he is very slow or he way underbid the job. The job was 3300 sq ft of wall space of a house the owner is flipping to make a rental property. So I would say it has your average amount of cutting and no high ceilings. How long should it take to hang and finish this amount of drywall. He is going to have about 140 hours into it and has a guy that has helped him about 80 of those 140 hours. After he pays his help he will only profit $1600 which is only roughly $11/hr which is horrible. So either he just way underbid it or he needs way more practice at speed. What would you charge for this?
