This NYT article comments on the struggles of a $4,000 suit maker, a true craftsman making completely custom suits in New York.
Even at that price as everything is hand produced he can only make so many suits, the cost of 1 suit or 10 is the same as the inputs are the same. There are no efficiencies.

I suspect is starts with technology assistance, what are the 20 little optimisations that improve the process? Rather than looking at factory like churning out, how can technology help him personally. Rather than replace, embrace the craft.
