How does a person finish drywall?

After 10+ yrs of doing reno`s I have found the best way is to let someone that loves to do it , do the job in the first place.What may take you 8 hrs just to put the boards up may take me 4 hrs and a pro will have the boards up and the first coat of mud up in less than 3 hrs. Well worth the money to let a pro do it.But if you want to DIY then the box stores have cles that will show you the basics.
