Supplementing business

Hello, I am new to this forum and was looking for some insight. I have been working for a general contractor for 2 years who mainly does Roofing and my main role in the company has been supplementing insurance claims which I have done very successfully. I am interested in opening my own business and doing this for many roofing contractors in our area. I am not sure if this is even possible or where to begin. Any ideas would be helpful. Thank you.

Where are you located?

I am in Idaho but the place I currently work for does work in 5 states.
