You'll generally find this forum is focused more on technical welding solutions than business/contracting advice. There are plenty of people here who run businesses and will tell you: business knowledge is a distinct discipline from trade knowledge/skill. It's not realistic to answer your question without knowing more about your operation. What is your business structure, tax obligations, effective overhead, historical pricing in your region, job costs, gross and net anticipated profit margins. If you know the answers to those, you'd know the answer to your question, if you don't there really is no correct answer to your question. One of the real fun parts of running a business is learning just how much nerve wracking risk you're willing to take and learn from. Best of luck.
