Hello,
My name is Jasmin and I am working with blender for several years now. I am very confident to be able to help you with that project. I can create a blender file just for rendering, so you can just drag your metallic object in there.
But I would need some examples on what you didn't like on your previous attempts, so I know, what the issue is.
If you need any more info, please contact me via chat.
Best Regards,
Jasmin
