I've done all mine in my basement that I'm currently finishing but I am by no means a pro. I took my sweet a$$ time. Anyway, the tip that I got time and time again when looking around for drywall contractors before I decided to do it myself was to call painters and ask them who doesn't the best and timely job. Painters are the first people in after drywall finishing and get to see the finished product up close and personal. Not sure if that helps but good luck.
