ISO Clay or Plaster Sculptor

Replicate existing ornate Celtic-like design from pictures of a pillar cap. Cap is round at bottom and square at the top. One-sided model or four-sided model, sculpted or carved to match existing piece to be provided. New model is larger than existing piece, does not have to be identical but as similar as possible. 3D design with intricate interweaving patterns. Would need to be shipped to Maryland. A scan of the piece was done to try to replicate the design with CNC machining but scan did not accurately copy detail.
