Shipping electronics from Shenzhen, China to Busan Port, any forwarders available?

Hello, we are a used car exporter. We install Android All-in-One electronic devices in our export vehicles before shipment, and due to the recent rise in raw material prices, we are planning a bulk purchase. The shipment consists of 240 units of 9-inch devices and 60 units of 10-inch devices (based on individual boxes), and we are looking for a forwarder to handle the transport from Shenzhen, China to Busan Port.
