Compose a business letter to an external customer. Your creativity can show in this assignment, since you will make up the reason for the contact and the audience to whom it is written. You will not have letterhead to use, so don't worry about that. And don't be concerned about signing it, since it will not be mailed. The biggest concern is that it sounds professional and is presented professionally (with no errors). Assume that there are no enclosures; and since you are the typist, no typist initials will be included.
