3D Model for Skull Chalice Mold

I'm seeking a skilled 3D designer who can create a file suitable for casting a plaster mold for ceramic slip casting. The project involves designing a mold for a kitchenware item - specifically, a skull chalice. I have 3d files for the skull chalice, split into 3 pieces (top/cup part, middle/neck, bottom/base. the design is pretty intricate. I attached an image that shows the item as a whole.

Key Requirements:
- Proficient in 3D modeling software
- Experience in designing for ceramic casting
- Can create detailed and functional kitchenware designs
- Understands the requirements for creating a mold

Please include examples of previous similar work in your proposal. Looking forward to working with a talented designer on this unique project.
