Silver-Plated PETG Urn Print

I already have the STL file for an urn that sits right around 11" × 11" × 11". What I need now is someone who can take that model from digital to finished piece:

• First, 3D-print it in PETG with a clean, even surface. The urn will live outdoors and will hold ashes, so strength and weather resistance are critical.
• Second, electroplate the entire exterior in sterling silver, achieving a bright, mirror-like shine. A durable under-coat (nickel or copper strike) that guarantees adhesion before the silver goes on is fine—whatever technique you normally trust for long-term outdoor use.
• Finally, incorporate a well-fitting threaded screw-on lid so the contents stay secure yet accessible.

Please handle any light sanding, polishing, or buffing needed between stages so the final surface looks flawless. When you’re done, ship the finished urn to me safely packed and include a quick note on basic care for a silver-plated object that will experience weather changes.

Let me know your turnaround time, the plating thickness you aim for, and any questions you have about the file or finish. Looking forward to seeing this piece come to life!

Additional Information

- The client would like to review the 3D-printed PETG urn before proceeding with electroplating.
- The target completion deadline is 45 days, although earlier completion is preferred.
- The client is looking to balance cost with durability and weather resistance.
- The client is open to the freelancer's expert recommendation on whether to use a thicker electroplated silver coating or apply a clear protective coating over a thinner electroplated layer to improve durability and weather resistance.
