How can I find an insurance company that will provide commercial
liability coverage for my business? My business is Home Demolition
Sales. I sell items from homes slated for demolition to retail buyers.
For example, the items sold include the home's floors, doors, kitchen
cabinets etc. The buyers remove the items on there own under my
supervision. I need coverage to protect myself and   my business. The
insurance policy also must allow me to name the owner of the property
as "additional insured" for the time period we are in the property
removing items. That is typically one day. In summary; what insurance
company (or companies) will provide liability coverage for my home
demolition business and what is the cost estimate for 1 year of
coverage. A list of at least 10 insurance companies would be ideal.

You should have insurance now -  just go to your current insurance
agent.  They will either be able to write the insurance or make a
referral.
