Pizza Delivery, Non-Owned & Hired Auto
Companies somtimes have an contact with email/number under the 'ask a question' field. If not there will always be a number or website also listed on the product page. Good luck!
Not on a personal lines policy. Progressive will cover it on a commercial policy.
Also I believe State Farm will cover it with a business use endorsement.
Lastly try USAA. I have seen them on several claims. Not sure if they knew what they were writing or not. But they might be an option.
All the ones Krishoney posted write only hired and non-owned auto and commercial owned auto in conjunction with all other lines.
