You will need Workers Compensation and General Liability Insurance. In addition many times your are asked for additional add ons like "additional insured" and or "waver of subrogation", etc. You need to find a "BUSINESS" insurance agent, not an agent that only sells auto and home owners insurance or that wants to add it on to your existing polices. The agent should be able to tell you what you Workers Comp codes are just by you descriping your work. They also have to be licensed in the state you will be working. I had insurance but it took me 10 years to find a good agent.
