I've designed a vast number or logos over the years. A logo or corporate identity is an extremely important element of your brand identity, and it's design should reflect your company values and character. It's the official icon that represents a business, it's ethics, beliefs, and it's goals. It's the icon that symbolises what your company stands for as a brand.
The first (and arguably the most important) contact most customers have with you. A well designed logo can be timeless and a tremendous asset, drawing customers to you and keeping your business memorable.
