Hi Platon,

I'm not sure if this is what you searching, but I could need someone who make a low poly version of the robot I'm using as main character for my FPS game.(Got it from Blendswap.com)

What you need to to, if you want, besides from decreasing the polygon count, is to bake a normal map. Baking Textures is a very useful technique when creating game art and there are plenty of tutorials out there. The textures already exists so you don't need to create them, this seems to fit you since most of the models you show on your site are not textured.

This is the source of the model: http://www.blendswap.com/blends/view/19040

And here is a short video showing the animations: http://youtu.be/RTcBAZNbaeY

If you are interested(hope so), just let me know and we can discuss the details.
