don’t forget that a business card has two sides. I have put my basic information on the front along with logos of methods I teach and have added additional data on the back. If you feel it is important to mention that you are insured, I would put it there.
Personally, I also chose to design and print my own business cards which gives me a chance to change in any direction I want and don’t have to wait until I have used up the first 1000. That will also enable you to modify business cards if you go to a specific event where you want to tailor the information to the expected audience.
