Hey GrimJudge,
Thanks for posting that request! A quick heads up: $100 is pretty low for a city map, especially if that price includes the copyrights. People tend to spend dozens, sometimes hundreds of hours laboriously creating a map, and $100 just isn't a fair compensation for all that work. However, I'm talking about somewhat larger maps (A5 and up, or roughly 4 megapixels and larger). It might just be you're looking for a way smaller map, a bit like the example you posted, in which case the price might just be right.
Can you give some more information about how big/small you would like the map to be? Either in metric units, imperial units or pixels?
