i CAN HELP YOU IN Hong Kong we have a friend with studio and factory in China
go to the members page and share info.
Start by making the clothes you want to sell.
IMO: you got alot of cutting and sewing to do, it will require you to work 16hrs. a day, 7 days a week.
When i say 'work' that means producing product, NOT walking around handing out business cards.
Good Luck !
