It all comes down to TIME versus price.
It depends on how many GOOD jobs a day you can do, versus the amount of money you can charge in your area, versus how much business you have coming in every day.
It also depends on how many jobs you can do AND keep up on all the businessman functions.
If you have a wife who can take care of the business end of it you can do more jobs and make more money to support both of you.
Every minute you spend not actually working on a gun is lost money.
You have to spend some time talking to the customer and doing other things.
Fact: There are no rich one-man gunsmiths. Want to make good money? Be a Wilson or one of the guys who run big multiple gunsmith shops. They do little to no gunsmithing themselves, they're businessmen.
