Best way to ship stuff from Germany to Jo'burg?? (Johannesburg)

Dear all

I will be moving to Jo'burg in the next couple of weeks for my new job. I have a bunch of moving boxes that I want to take with me. No furniture or any bigger items. Do you maybe know of anybody who would like to share a container or do you have any other suggestions for me? I don't mind the transport taking a few weeks but it should be safe and insured. Most logistics companies that I have contacted won't take small loads and that would leave me with very expensive express services...

Thanks a lot in advance for any advice. Looking forward to meeting you guys at one of the next get-togethers.

Susanne.
