Region based Keywords Search

Hi all,

I had been thinking about developing a crawler that could fetch the data from various search engines based on keywords search with geolocation using google maps.

The idea is, I would type in a keyword like "Radio controlled Toys", and on a google map it would show me where in the world people are searching for this keyword or similar keywords.
Lets say people in Germany in the city of Berlin are looking for the keyword, it will show me on the google map, and based on that I can set up an advertising compaign down there.

Any ideas about the product?

Are there any websites providing the service or products?

Thanks

that would need some hardcore coding if you arent one yourself and have the budget can hire a bunch of coders to do it for you, it sure sounds like a complex task
