MorrĂgan, if you go to your local post office you can prearrange to have packages delivered there instead of your residence.

Why? In the name of feathers and fedoras would you not know the schedule of the firm you are staffing? If someone who is motivated to work for you suggests their willingness is contingent on schedules, why not make sure you know what the fuck you're talking about? I have serious feelings about subcontractors. Serious.
