2D Artist for Tower Defense Game

I'm looking for someone to create or sell me premade assets to me for a pretty simple tower defense game.

Here is the short outline.

Futuristic Tile set in the midst of a war.
2D Top down, static, not ISO or 2.5D.
Turrets can be anything from classic turrets to tanks to little soldiers. Open to suggestions here.
Prefer Tiles over giant backgrounds so I can make new designs quickly.
Over all style would be pixel, I think the game Granada on the Genesis is perfect for the style, but I would want better graphics, much more details than that. But it's a good start. http://www.retrogamer.net/users/796/thm1024/granada.jpg
