My family used the service of a forwarding agent in Puchong (Selangor) when they migrated to NZ few years ago. I can't remember the cost already though but it was via ship and took around a month to reach so we send it around 1 month earlier and it reach just in time for them to move in and settle down.

Anyway, let me know if you want their contact, don't know if it'll be any help to you since it's in Selangor and not Sabah.
