I am a driver driving a minivan, and I want a business card for the development of my business. I don't know how to write.

These three are enough. It doesn't matter how to write the business card, as long as it can be contacted. You should design the cover where you design the business card. It should be novel and impressive at first sight. Remember that you are very important, otherwise people will be in trouble if they throw it away in the future. Go and design one. The content is not important, it is nothing more than those things.
