So someone out there must have made a courier-as-a-service website for this?
Sign up some people to be on standby, with a passport and a list of countries they have visa for, list them with their current location.
Person signs up to potentially make a few grand if they get the call.
Firms who are in need of a person throw in the money and the tickets.
Does that work? If I need something carried by a person from London to NYC today, what do I do?
