A problem to sort up (another option: A problem to solve)
Hi everyone. I'm writing to you even though I'm quite busy and overwhelmed right now. This is because I'm preparing everything I need to take the graduation photographies (better: pictures) of my college classmates. This will happen next week at my college and I've got it all prepared except one thing: the outfit for the students (better: the student outfits).
Despite there being more than a week left until the event, I'm becoming (better: getting) quite nervous because I'm not sure about how much time is needed to prepare for such a thing. I've already sent messages to different businesses that handle the matter and, by now, I'm [just] (not required, but more natural) waiting for any answer. If nobody answers me before (better: by) the end of today, I will start to call all of them until I can have an answer.
