Give me the relevant information and I will return a design that is effective, clean, simple, and easy to read. These are the first invitation for a potential customers to inquire about your business. The purpose is to get the person to call or visit your business so that you can service them properly. With that in mind, the contact information should be large enough for people to see. Too many business cards have the print so small that the card gets thrown in the trash, your money wasted, and no new business.
Do not call the number on these cards, some are no longer working.
