There's a site called the Jalopy Journal who have a board similar to this, but a little more "intense", shall we say. It's peopled by hotrodders, customisers and enthusiasts. Some serious high-budget work featured there, too. You my be able to search their topics to see who's had chrome plating done by whom. I've heard dire warnings to people to not just sign up and charge in asking questions which may be already answered in their archives; lurking a little first is perhaps better.
