Moving internationally has never been easier thanks to technological advances and better supply-chain management by moving companies. While this may be of some comfort to you, there is no doubt that the move itself is your immediate concern.
What is important to remember is that you want a company with a stellar track record that is fully bonded and ensured. Furthermore, they must be capable of taking care of customs and excise if it is a factor, and that they can arrange storage facilities for you if it is required. But as with everything, plans and dates can change, so make sure that you are aware of their refund policy before you make your final decision.
