Comparing these companies?
Hard to place? I find who's likely to take it.
This directory lists every licensed insurer; it doesn't mean I'm appointed with each one. I compare the companies I work with that take risks like yours. I'm licensed in all 50 states and Washington, DC and your request stays with my agency, not passed to another agent.
