Insurance Carriers above 4 stories?

Hey All, I don’t know if this is highrise, but I have a 5 story hotel that wants a quote. The issue is my insurance only goes to 4 stories, and my agent has one carrier that would cost me 3000 a year instead of the 950 I currently pay. I would wfp the bigger buildings and I am solo. Anyone out there know of a different insurance carrier in the US that would be less? I would like the option to go to 6-7 stories if possible. My agent is with insureon and the carrier is Markel Evanston.
