My parents used to use Tony Thompson to tune their piano. He is a local (Raleigh) jazz musician and keyboardist who used to also tune pianos to make some extra money. I am not sure if he still does piano tuning but you could certainly try him. If he doesn't tune pianos anymore I am sure he could point you in the right direction of someone who can. Sorry, I have NO idea about the price. Here is a link to his website.
