Errors and ommisions. It's a kind of professional liability insurance that covers breaches of professional duties the same way that malpractice insurance covers doctors and lawyers.

Professional associations are a good place to start. The other thing to do is look up a good local insurance broker, not an angent or agency. You don't need someone as large as Marsh & McLennan Companies, but someone like that. You can find some nice local or regional broker who will get you the best coverage at the best price.
