Perhaps what would be helpful to understand costs associated with doing work in our current society. How much labour, materials, equipment amortization and other overhead do you think this painter/sandblaster would incur to complete your frame. Do you really think $250 is a reasonable number. Now imagine what the number would be if the shop complied with all safety, environmental and other regulatory requirements. It’s people who are constantly grinding for the bottom dollar which is causing the exact behaviors you are complaining about.
