Transparent 3D Human Model

I need a 3D version of the attached 2D image. It is a human body that needs to be transparent. Inside the body are sections that I can set the color on, so they need to each be individual models. I am going to use this in Unity 3D, so if you have the expertise to do a Unity Prefab that would be best. Otherwise a FBX would work. It will be used on Mobile, so a balance of good looking and low poly count is important.
