I used SevenSeas to send 49 boxes of my shit from Hong Kong to Australia when I left HK. The price was very competitive, service was great, they delivered free boxes to my apartment a few weeks before pickup, everything is done online, I could even use their website to track the container ship it was on and where it went on it's 8 week voyage around the Pacific (was docked off Shenzhen for a bloody long time!).
The bloody Australian customs detained my shipment for a while because my Dyson vacuum cleaner had a bit of dust in it and was a biosecurity hazard. They charged me an extra AU$55 cleaning fee which I am sure is just some idiot opening and emptying my vacuum cleaner. But not SevenSeas fault.
They picked up Dec 12th, delivered to Perth Australia on 19th Feb. More or less on schedule.
If you only want to ship a few boxes, they will do that too. I am sure the price per box will be higher but check their website and get an instant online quote without any bullshit having to leave your name and number and then some guy calling you back.
