This looks remarkably similar to a previous post about a letter to a neighbour about a forthcoming party.
Again, as I did with that post, can I remind you that the forum rules state:
"Please don't ask us to do or correct your homework..."
With work like this, it's better that you do it yourself, have it marked and corrected by your English teacher. If, after that, there are still points about it that you don't understand, then ask us if we can help or elaborate.
