Business or General Liability Insurance
Each state has it's terminology. If you search for business insurance your city's name look thru the search results.
I get biz insurance thru Safeco,$500 a year, not sure if they can write policies in your state, I have a theft bond also but it is thru a different company. $185 a year.
Some companies may require or ask you to have workers comp insurance, even if you have no employees or have employees-- I got this thru National____ it is/was located in Florida. Google workers comp you'll get lots of results.
Talk to the rep's take notes and before you pick a company look them up on google, look for reviews, check the BBB, check with your states insurance commission/licensing dept. also.
