Estimate for drywalll repair?

Dude fix it yourself. Razor knife,1.00, 1 piece of drywall, 5.00 , spatula and sandpaper. A palm sander would be perfect. Cut a square with your razor knife around the hole you have and take that out. Cut another square out the drywall you have and make it little bit smaller. Screw that to the joist and mud and smooth out the crack. Go back the next day and sand your area and reapply mud if necessary. Let dry then sand. Its about 12.00 of material and know how. You can do it. Look it up on the internet and save a bundle unless you're rich. I would charge 50.00 but I think other would try to get you.
