GreenStone Services operates on a common level of integrity.  If we provide a quote, and no change orders are required we stand by that quote.  

​

We don't change prices after we call to get an ok, and better yet our quotes are "Firm"  meaning if GreenStone Services calls you and tells you your computer needs XYZ and it cost this much to fix XYZ that is all it will cost you. Period.  If we miss something that is major or minor that isn't your fault that is our fault.  It is integrity and it is us providing the service you expect.
