I saw a lot of young entrepreneurs here having trouble to find reliable suppliers of apparels. In fact, most of large companies will be reluctant to accept small orders, and for small companies, they just want to make quick money, so usually they also will quit halfway. It is really hard to pick a reliable and responsible factory overseas. Now I have several recommendations to make.
For buyers, factory inspection is the most effective way to test a factory is worthy your time or not. If it's not applicable, finding an agent can work sometimes, especially when you know some guy in China or Vietnam, and they can recommend an agent to you.
