Face/Head 3D Modeler required

Hello community.

I need a specific artist who is really cool at modeling character faces, especially females.
I have set of sketches for female character and need head model with face to bee exact match to them.

Priority #1 is ability to perform hi-poly sculpture (Zbrush?)
Priority #2 is optional - retopology to game mesh and texturing.

You can mail me to with link to portfolio and preliminary estimation for this work.
