Jewelry printing prices

Hello, I have a local customer interested in having some custom rings printed in castable. He does his own casting. I was wondering if anyone has insight into a ballpark market value for the print… I don’t want to undervalue the print significantly, and I have no idea what he’d be expecting to pay for an alternative.

Thanks!

In NYC i checked couple of places that print jewelry-
for rings- one place wanted $25-$35 (for wax with solidscape)

the other place for higher resolution print in wax with solidscape wanted $80-$100
