Liability Insurance For The Self Employed

I am self-employed as a contractor administration. I am fortunate to land a lucrative contract, but the customer has requested that I wear a simple general liability policy. I've been to all the major insurers in the city, and nobody has heard of such a thing for a clerk. Ideas?

Hire a broker or independent agent who handles commercial insurance. They should be able to write a simple business owners policy (BOP) for you.
