This is an interim concept. The basis of longevity for a sub-culture is having our children marry each other. So in other words, this concept would serve only as the first generation of wives. Of course this is all in theory, but eventually foreign brides would be in direct competition with our own theoretical daughters.
I have no objections to this as a short term strategy though, except that opening a franchise would be unrealistically expensive. Opening a factory? Supposing money wasn't an issue I'd alter some aspects. I'd build a catholic church on site and require mandatory service. The work environment also sounds somewhat harsh, I'd allow women to visit or be visited by family. I'd also include English classes and perhaps communal chores for all female workers that would translate into home making skills, such as keeping dormitories clean and learning to cook.
