Career in Sourcing/Supply Chain?

Hi, is there a job like what I'm describing here? Basically, someone works on commission and travels to foreign countries to meet suppliers or customers. Maybe similar to a trader of goods, or broker. And this would only be on commission, no salary, making hours flexible. I have income from a business and don't need a full-time job. I'm interested in learning more about sourcing/procurement/supply chain because I thought maybe it would allow me to work while traveling abroad. I lived in Japan for almost two years, but would also be open to traveling to other countries. I can self-sponsor in Japan or Korea, and maybe some other countries. I just don't know what to look for or who to talk to in terms of asking about this, as no one I know is working in procurement/supply chain. Thanks
