Design 12 Characters for a 3D Mobile Game

I need 3D Rigged (humanoid) Characters for my Unity Game.                  Characters will look fun, humen.                  Character has to be designed in blender.                   I need facial animations for spitting. (Will be discussed before giving the job)                  For mobile devices we need somewhere between 1000 and 1500 polygons per mesh.                   Textures has to be light weighted.
