Does it make sense that the customers come along after they saw and recognized your ad,such as logo or business card?
Don't take it easy,that is very important for your company to have out-standing logo and design if you want to make success in business.
How I normally start with design is to spend enough time to understand you or your company in order to create design. You would feel it as if it could be your part of body . The design has to have reflection from what you do, I believe.
