I work for a 3D Design Company and I'm an expert in 3D Modeling, Texturing, Animation.
I can make high-poly and low-poly 3D Models depending on the needs. I work with UDK Unreal Development Kit, and know the issue of designing for 3D games.
I can develop an highly complex model of a trooper as the one in the image you have posted for 400euros.
Please contact me if you want to see a sample. In the meanwhile you can check my portfolio for some 3D design. Thank you
