Hi, I'm Ash. I'm a Unity dev specializing in 2D and 3D art/animation and generally use Photoshop & Blender.
I'm really interested in your zombie project. It sounds like you're looking for a few animations, which I can make for you in Blender before importing to Unity, hooking up the animations in Mecanim, and saving as a prefab to be imported easily, along with the individual animation/model files and texture. I can also rig the model first, if necessary.
You can see more of my work on my portfolio. Feel free to send any questions. Hope to hear from you soon!
