Realistic Human Head 3D Model

I’m looking for a skilled 3D artist to create a realistic human head model. My end goal is a clean, production-ready mesh that I can later texture and rig on my own, so the focus is strictly on sculpting and topology rather than advanced shaders or animation.

Scope
• One neutral-expression human head, realistic proportions
• Clean, quad-based topology suitable for further subdivision
• Separate low-poly (game-ready) and high-poly versions, delivered in OBJ or FBX
• Basic UV layout—no texturing required at this stage

I’m comfortable if you sculpt in ZBrush, Blender, Maya, or a comparable tool; just export to the formats above. Please keep polycount efficient and avoid artifacts or non-manifold geometry. If you have existing anatomy studies or portraits in your portfolio, that will help me gauge fit quickly.
