My friend recommends the guy below Marseth. He doesn’t have his address but here is his number. I’ve never used him but trust my friend’s experience. He is a metal finisher that sends out for plating but my friend says he is good for straight plating as well.
You could also try Walt at Micro Platers. I’ve used them for motorcycle fenders and other small items. They did a good job almost four years ago and were reasonable at that time. They are fairly close too.

The three below were referred to me by somebody long ago. I never used them but I tried to look them up online and give you as much information as possible. Two of them just have addresses from Google.
