Extra notes: I have two logos I designed (they are terrible) that I will supply as samples to give an idea of the sort of thing I'm looking for, just more professional is what I want and obviously designed by a professional designer. I would like to use the golden ratio in the design if possible so designers with an understanding of this and other design guidelines will be most appreciated. I would like a design that conveys modernity, a grasp of current techniques and principles in marketing and a sense of evolution in business, developing, adapting, changing to reflect current conditions. This is the principle of Evolve, adapting and changing to match data and advancing market knowledge, in order to survive in business.
