Historic Rococo Fireplace 3D Modelling Project

We are looking for an experienced 3D modeller / digital sculptor to recreate the historic Louis XV / Rococo fireplace shown in the attached photographs.

The model will be used to produce a full-scale (1:1) physical reconstruction for a museum exhibition in Zurich.

Scope
Faithful reconstruction based on the available historical photographs
Focus on geometry, proportions, profiles and sculptural ornamentation
Approximate overall dimensions: 125 × 110 × 33 cm
No textures, materials, UV mapping, rendering or animation required
Details not clearly visible in the photographs may be reconstructed in a visually plausible manner
CNC requirements

The final model will be used for CNC milling. We therefore require:

clean, high-resolution geometry
correct 1:1 scale
watertight/manifold geometry suitable for fabrication
no problematic intersections
logical separation into components where useful for CNC production
no CAM programming, toolpaths or G-code required
Deliverables
STL and OBJ files suitable for subsequent CAM/CNC processing
Native/source file (Blender, ZBrush, Rhino, 3ds Max or equivalent)
