Intermediaries usually charge, no matter what you do on board. I have met many intermediaries, but you should think carefully when choosing an intermediary. Many intermediaries are deceptive, but there are also legal intermediaries. I suggest you go. Look for Yinghai International Shipping Company headquartered in Shenzhen. They all have branches in coastal cities. If you want to find an intermediary, ask the head office in Shenzhen first and call you. 0755-2689680 1.0755-26896802.0755-2689820 1.
