Contact ex coworker

Today I contacted coworker from my previous company. He is a sales executive. I hope he can provide me more business connection. He worked for Kintetsu Intermodal Seattle about 13 years ago. His office is used to help building company to ship material to Asia.So he asked me to contact couple of his old client. He believed there are many companies in Seattle that ship building materials to Asia. I will contact them and take it from there.
