I search for something like this (without the buildings): Please klick here

A friend of mine and me too we develop a browsergame.
The developing is not the problem, but we need a map where the user cand build some house, like a harbour or something like that.
But we both can't design so we find this creat community, and we hope, that maybe someone here can held us.

We need a map like the image, with some lanscape and very important is the see. Maybe some Stones, Forrest, and some grass and sand.
Is that possible?
