Want someone to promote industrial product business in Vietnam

We are purchase agent in China helping users in other countries purchase from China, especially the industrial products like relays, switches, valves (solenoid valves, butterfly valves,all kinds of valves), transmitters, sensors and many other items which you may not have heard of. Basically, these products are usually used on machines, like power plant system machines, food processing machines, sea port controlling system, etc. As long as there is an automatic system running, there will be a requirement for these products. So the buyers are usually trading and engineering company, or factories. Many of the products in China are with very good prices comparing to that in Vietnam, we know this because some customers from Vietnam have been cooperating with us for more than 3 years. We help them to handle the purchase process in China for communication and product inspections to earn more profit margin and keep the business safe. We need someone to expose our puchase agent service to more targed users in Vietnam, like the B2B website in Vietnam or other platforms where Vietnamese trading/engineering companies and factory purchasers gather. This job only applies to natives in Vietnam!!! When applying the job, do please introduce your proposal that how you will help with details.
