all sorts of services ranging from $12/hr for some High School kid to repair your computer, to $75/hr shops that have better trained experts. Many companies have a call for an estimate and the rates differ based on organizational income, or if it is a home user.
My rates were $35/hr which I found out were too low, but not the lowest. I like the idea of a flat fee, no nonsense and you know up front how much it will cost to repair and write the invoice in advance. Then have them sign a standard contract, collect the $200 and we can work on their system. Our marketing ploy is that we hire experts with years of experience, and those experts do not work cheap. That they will get a better quality from our experts than most repair shops. Total Qaulity Management, another concept I learned in college. We won't be flipping burgers, we will be broiling steaks.
