I'm in Canada near Toronto and I will be using an insurance company called HMS Insurance. They quoted me:
$791 for 1 year of $500k liability insurance for a single craft for commercial use in built up areas. Also covered up to 1600 feet ASL thou in Canada we are limited to <300 feet. Some SFOC will grant special permission for up to 1000 feet and night ops.
$500,000 liability $700/year
$1 million liability $800/year
Physical damage (fire/theft) $350/year
Your quote will be different due to your specifics but this will give you an idea.
I have contacted about 5 diff insurance companies and most of the other ones were quoting $1500+ min for drone insurance.
If your in Canada you could look them up here's the contact info .
