Well, there are some ortographic mistakes (among others, you repeated "contract" when you probably mean CONTACT). About these mistakes, although you can correct them with MSWord, i wouldnt worry so much. But then i see that along the whole text you repeat many times some words( communication, convenient/convenience, parent,...). It can make the raters think that you are saying the same thing all the time. Try to use other words if you are going to repeat something.
Besides that, i think that you should rephrase some sentences, because they seem to be too complicated. Try write your ideas as clear as simple, even if that means to write more simple sentences. It is better to write simple but right sentences that confused long sentences..
good luck with the next one!
