Find a small/local broker. And/or reach out to a company that is similar to yours and ask for the name of their insurance broker. I had a similarly hard time because my company works with kids. A lot of insurance companies just don’t want to bother, but ultimately it comes down to the broker. Brokers at big companies will give up at the slightest obstacle and ghost you after putting in minimal effort. A small broker that actually understands your company and what you do will be able to reach out the right insurers and navigate any obstacles.
