I don't know your flight experience but this company,
www.hoxton.com, got me covered for about $1600, for liability. Their requirements was of course a multi-engine rating. I needed 20 hours of dual, since I wasn't multi-engine rated, at the time. And Basic Med is okay. But an increase in cost at age 70, I'm 67. I added, after receiving my rating, HULL at $30,000 for additional $1600. I now have about 120 hours PIC in C337. Now premium is around $2600. I hope this helps.
