HELP

I'm a teacher in Zhuhai, CHINA relocating to Sohar, OMAN and I have about 100 kg of clothes, books, and miscelleanous stuff which will fit in about 10-12 medium sized boxes. I want to send this via ocean cargo. How do I do that??!!! I can't get anyone to quote me anything other than air cargo and that is over $2,000 USD!!!!
