Backstory: Communicating with vendors overseas can be troublesome due to communication barriers. Additionally the time zone difference prolongs the process.
The Idea: Overseas consulting for ecommerce businesses.
Deep Dive: You would build a platform for vendors and customers to sign up and select a coordinator, someone who speaks both languages and is proficient in the business area. This person would help facilitate initial meetings and monitor email exchanges. As this grows, you can keep track of communications in the platform as well as user ratings and invoices.
Validation: Currently a client deals with overseas vendors and they often leverage a friend that speaks Mandarin and has a solid base of contacts overseas.
Monetization: Once payments flow through your platform, you would take a cut.
