International Express shipping to South Africa

Good day! I seek the services of a company skilled in international express shipping to South Africa. I need to ship a rather small package from Melbourne, Australia, and if at all possible it should be delivered by the end of next week. Can your company meet that delivery expectation? By a small package, I am talking about a package that is 152 mm by 102 mm by 77 mm and weighs less than half of a kilo. I do hope it is not too small to ship. I am sort of concerned that it may become lost in transit. Can your company provide any sort of a guarantee that this package will not become either damaged or lost? Can you also guarantee this package will be delivered on time? This package is ready to be shipped, so if you have a drop off location that is near to me please send me the address and the hours it is open for business. Thanks for sending me this information.
