Second Hand Field Worker Buyer Vietnam

I am looking for someone close to Hanoi who can travel to Hanoi/the surrounding areas to visit second hand clothing markets such as flea markets and second hand shops. I am interested in purchasing second hand women's Japanese clothing as most of it gets shipped to Asia and resold at your flea markets. I would ideally need you to travel to these markets, find women's clothes with Japanese labels, and send me pictures so I can tell you which ones to purchase.
