Vista Print usually gives you the option on the back of the card to have it blank, write your own text on, have a calendar for the year or an appointment booking.
I have typed my own text because a lot of people can see what you have to offer before rining. My card has my services listed on the front - massage, waxing, tinting, spray tan - and on the back stuff like - Bookings avail day or night - Full body waxing for men and women - group bookings avail - I can't think of the rest off hand but I've got about 5-6 lines.
I love love love vista print. They always have fantastic deals.
