Abstract Human Figure 3D Model

I need a 3D artist to create a solid 3D model of an abstract human figure sitting or reclining, suitable for subsurface laser engraving inside a crystal ball (approximately 60mm in diameter).

Requirements:
- Format: .OBJ or .STL
- Watertight: No holes or open mesh
- Geometry: Clean solid, no textures or colors
- Engraving-ready: Designed specifically for laser engraving, not 3D printing
- Reference: I will provide a photo or sketch

Ideal skills and experience:
- Proficiency in 3D modeling software
- Experience with laser engraving design
- Ability to create abstract human figures

The style is relatively simple, no need for extreme detail.
