Dude, I finished my own basement. You pretty much just make sure everything is at 90 degree angles to each other and then just put twice as many nails/screws in everything just to make sure. It really wasn't that hard. But then again, I'm pretty much really good at everything I try. But for real, don't go get permits for all that crap. Waste of time/money. I finished my own basement and sold it the next month without any problem from inspectors etc. My in-laws went the "legit" way with the permit thing and the inspector wouldn't "certify" it because my dad-in-law didn't have the little plastic cover thingies on the light switches yet. GMAFB!!!!
