It used to really bother me when a customer would question my price or tell me they could get it done cheaper. It doesn't any more. I have to make a profit. If I don't, I won't be in business at all. The "good" customers, the customers you want, will pay your price without question because they know you do quality work and if they have a problem on that installation or need something else, you will be there to help. The guy working for wages without insurance won't be there and probably will have a new phone number later.
