Keyword Search Volume Research

Greetings, We are looking for some simple information and we are willing to pay consulting fees to get it. Our main question is: where may we find keyword search volume for specific counties? Is there a tool or service that narrows down search engine volumes by country? We have a good idea of worldwide volumes and US volumes (overture/yahoo tool, google) but our target market for a new project is in Western Europe and Eastern Europe. Preferrably the volumes will be given on a per country basis expressed as a sum of all search traffic. If they were to be broken down by search engine that would be even better. We are willing to pay for a referral to a tool (free or paid), buy a tool for this or even possibly hire a contractor to create a tool to carry out this function. Thanks, we look forward to your response.
