Some ideas that I have thought of are quotation marks or speech balloons combined with film/video elements (play button, camera, slate, etc).
I could also go with another idea if you can find something that is simple, yet powerful. I would not mind a character, for instance. I am also thinking that the letter Q could play somehow?
Just brainstorming... I will not necessarily award the design that illustrates my thoughts, but one that surprises me with taking this concept and creating something SIMPLE, FRESH, SLEEK and FRIENDLY.
I would like the business cards to be a square instead of a rectangle, with rounded edges. I am thinking a solid color on the side where the logo is, and then a neutral off white on the other side with the info, but I am also open to fresh ideas.
