This may be a classic "bad idea" without some additional layers of security for precisely the reason you might intuit, drugs and other contraband. I have been a heavy user of courier services in the recent past (having been involved with media/PR agencies) and I know from experience that courier services in NYC do not and will not work with you if you haven't set up an account and/or don't have a physical place of business for them to pick up from. Try walking into a courier company's office with a package in hand and they won't take it from you without an established account. Granted, you could argue that makes for a business opportunity for Uber, but in my experience as a long time NYC resident when you see safety measures and precautions like that which are ubiquitous to business practices there's usually a reason, namely that if there's any way at all to take advantage of a situation in this city there will always be 11 people lined up to do it within seconds.
