Professional Indemnity Insurance

MDJO_2

Hi
I have the opportunity to do some freelance advising for a company (in additional to my regular job) and have committed to 10 days per year. The company does not insist on, but strongly recommends Professional Indemnity Insurance and Public Liability. Public Liability is not a problem as I am getting quotes for c £40 per annum, however PI insurance is coming in at c£160 -£200 per annum. At present I have only recieved one job from this new company at 2 days work, and the work is not exactly flowing in, so i was thinking that i may not achieve the full 10 days. I was therefore wondering if anyone knew of an insurance company that would offer PI insurance on a project x project basis. I have googled this several times, but seem to be just bringing up companies offering annual quotes.
Many Thanks in advance
