Blender file needs improvements (24 Hour Turnaround)

Hey, hope all is well! I have a Blender file that needs a few final refinements. The project is around 95% complete, and I'm looking for someone to finish it and provide the final animation export. The changes I need are: Make the sides of the pendant the same colour as front of each pendant letter Add a subtle sparkle/shimmer effect to the top section of the chain to give it a premium Jewellery look. Make the letters slightly bulged, matching the reference image while keeping the existing design. Ensure the overall finish looks like premium Jewellery with glossy enamel and reflective chrome. Once the changes are complete, I'll need: The updated Blender (.blend) file. A high-quality video export of the animation (4K preferred, or the highest quality available). The animation rendered with smooth lighting, reflections, and anti-aliasing for a clean, professional result. I've attached the Blender file and a reference image showing the finish I'm aiming for. Please only apply if you can get this done in the suggested time frame.
