I used to have a house cleaning business 10+ years ago and my insurance guy helped me - so I'm not real familiar with who's the best to go with, but you might want to start here:

Bonding

Bonding is an insurance agreement guaranteeing repayment for financial loss caused to the covered organization by the act or failure to act of a third person. Bonding is used to protect the financial operations of companies, unions and independent contractors. Many industries require one to be bonded as well as licensed before they perform their work.

Generally these bonds are called Surety Bonds (or Fideltity Bonds depending on your industry) and your state website will generally tell you if you need one for whatever type of business you are doing and how much coverage you need. For example if you are a Notary Public in CA you need a $15,000.00 Surety Bond.

Wikipedia has a good article on Surety bonds and how they work:

Basically, it is to financially protect your clients in the event that you fail to perform.
