Who told you to call State Farm, all the insurance company's mention write for homes and cars.
In order to get business insurance you need a commercial insurance broker and yes expect to pay a lot.
No one told me to call anyone, we have insurance through them so I figured I would check with them first. As stated, it seems like other people have insurance through State Farm and others. They do offer business insurance just not for me because of my relatively new business. I also called several brokers who also couldn't do anything. I finally found a guy who could help me. Its not a big deal, just a pain in the ass. I could try and be shady but that seems like poor business to me.
