What do you have in mind for the style and theme of the business card?
The design must be clean and modern, incorporating some of the brand colors. Just because the design is modern doesn't mean they're isn't an opportunity for creativity. Try to imagine something that appears professional but doest appear identical to every other business card out there. It also should garner attention. Size should be standard business card 3.5 x2 inches.
The two attachments are just examples of cards I like, not necessarily exactly what I am looking for.
