Prop maker / model designer required to recreate screen used prop replica

Hi

I require 6 (but possibly more) glass balls making with either paint or decal design added.

The 'orbs' are to be used as drinking vessels so should have a slight flat bottom allowing to sit nicely on a flat surface

I do not have specific measurements but I do have screen stills so the maker should have a good eye for guessing sizes and dimensions!

they do not necessarily have to be made from glass but they should be clear. so perhaps strong plastic as an alternative.

thanks
