Need a parallax map artist

[Gyldstrand]

Looking for someone who can produce a map with a dark and grungy feel to it. I only need one really large map with some unique areas or a few small maps that link together to create a setting. An isometric view is what I had planned but I am open to any art style that isn't the default tiles. I am making a prototype demo using these 3d rendered sprites so I require some "realism" in the look. Pretty easy to do with some textures. Doesn't have to be perfect, just has to look decent. 

Edit: I just need the terrain and walls. No objects or buildings. Very natural.
