my father almost went into it. Found a shop that charged for repair work, the guy doing the repairs charged a lot and often put in parts that didn't need to be replaced in addition to ones that did. Sort of like an Automotive Garage that finds all you need is an air filter, but says you got to replace the carborator and the air filter. So my father decided to go to the phone company instead and went and installed computers used with the phone system.
I am sure that with your honest reputation, that you can get more business than a crooked TV repair shop. The only trick is getting the word out to people that you exist.
I doubt that repairs on electronics will be outsourced to India, takes too long to ship things out there. If it is needed to be done on-site or on the bench, you need someone local to do that.
I hope the shop doing the repairs is not crooked. I hope they give you a reasonable price. Good luck.
