Commissioning a Head Morph

Setalia

At some point in the near future, I'd like to commission a custom head morph, but first I want to make sure I save enough money to afford it before I approach anyone for this. How much should I expect to pay for a Genesis 9 head morph, if I offer reference images? I'd want a morph specifically made for me only. And could anyone recommend some excellent creators?

 

Thanks.
