Ian could you perhaps list one or more of those enthusiasts that make proper maille if you think they'd be interested in a job?
The only one in the US that immediately comes to mind is Erik D. Schmid. Whether or not he takes commissions anymore I couldn't tell you. I know Mac has done maille tailoring in the past, I'm not sure if he made his own rings or anything like Erik does, nor do I know if he touches maille anymore. Erik has become a bit of pariah in some circles, so I'm not sure how that has affected his maille making. I know that's not very helpful, but it is largely why most everyone resorts to tailoring the Indian stuff now.
You can see one of the European maillers working his craft here at 21:45 in the documentary The Reenactors (English subtitles available via the CC button at the bottom)
