I had a neighbor who hung/finished for a living.
it was great..........I'd go buy a pile of drywall (like this one), and some beer & hoagies.
He'd come over and just start running around with sheets of drywall and a screw gun......BRRRRRRTTT..........BRRRRRRTTT.
Then he'd come by with his finish tools and make a big mess on my floor.
I'd clean up the mess and then I'd have all new drywall hung and finished.
Drywall is EASY!!!!
