I recently just engaged macrotune piano services for my grand piano tuning and took up a package with them for twice tunings per year. It worked out to be just $90 per tuning. Its consider cheap compared to others. And their service attitude are excellent. Steve the tuner explained alot on the piano maintenence and is very patient. Recently they just set up their facebook page at https://www.facebook.com/macrotunepiano maybe this will help.
