create 7 x 3.333 image for store front sign

eventually, the image will be about 7 feet by 3 feet 4 inches. He likes his logo and text, though it can be changed slightly, but would like the sign to go with the card that is included. his idea was have the butterfly sitting on top of the "D" and have the text go across in a single line. Then have some other subtle design in the top. You do not have to follow this idea. The final result should probably be in vector form, since it will be used to create a large sign. We would also like a photoshop version. Please submit a simple mockup of what you think the sign could look like. The best idea will be selected to create the art.
