Errors & Ommission Insurance for Web Portal - Suggested providers?

I'm getting ready to launch an internet portal. I want to have Errors and Ommission insurance in place... However I'm having trouble finding the right provider... (Many are more geared towards more traditional "professional" service providers...). Is there anyone out there that has obtained an E & O policy for a web-based business (ideally an internet portal) and can recommend suitable providers. These policies are fairly time consuming to complete - so I'd like to narrow the search ....Any/all suggestions appreciated...
