Custom designed Light

[elltel]

Hello Forum,
I am trying to find a builder/engineer to build a custom designed light light. The base of the light is marble, the armature is metal (brass) with the wire inside the armature. The shade is made from parchment and wire.

I think I could make the shade element of the light.

I am just trying to find to find some to help with the shaping of the marble and custom making the armature. Can anyone point me in the right direction?

Many thanks
