First off let me say that I know absolutely nothing about this topic and have never run a shop, but here goes anyway. Seems to me that you should be able to put up a surety bond of some kind and insure yourself that way. At close to $3k a month for liability insurance premiums seems you could afford to a $3k deductible with the bond to cover major loss or liability. Then you could buy a simple theft and fire insurance for the business. What say you? Am I full of it or just naive?
