Aurum is not RTW. It is MTO. Information about the lines have been mentioned quite a few times in this thread.With his plans to open a webshop, he is setting up Argentum as RTW from the preview he posted. Unless, he is also planning to put a RTW for Aurum, it hasn't been announced yet as far as I know.
If the CM side has its ballers that can regularly meet up with these Italian/English tailors and cobblers, do multiple commissions in one visit, and has vast knowledge/familiarity of their products, then I think uzairh is the their equivalent here in SW&D.
To be honest, I am also getting curious who uzairh is. I do know nicelynice has met him.
