Honestly, the first time, you just have to get one customer. Once you do the job right, they usually say, "Thanks so much! Guys this person is really fast and trustworthy!" So that obviously helps.

It also helps to offer collateral, because then it ensures that if you steal their card, then they have one of your cards, too.
