Suggestions for Marketing/PR compaines for Web Startup

I basically want a "Razorfish" experience but on a much smaller (and cheaper scale). We are funded so not looking to do this on a shoestring but at the same time we are still small-time and cant break the bank. I like look/fee of http://www.e3.co.uk in the UK but want a Firm with experience working web startup's. In a nut shell show me an small agency (can even be a single person agency) that has a strong background working with known larger agencies, is now doing their own thing and can show me examples of start up's we now all have heard of, but we didn't know of them before XYZ Agency got involved. Thanks ;-)
