I’ve heard this question before. As my expertise is in business analysis and development my short answer is always yes. I have dabbled in web design and I can recognize good design from bad but I would not classify myself as a Graphic Designer. I am always in awe of the individuals who can listen to a client’s description of who they are, what they do and what they want their site to look like and turn it into a beautiful functional design.
After reading the article Why It’s a Good Idea to Hire a Graphic Designer on the Design Theory website I now feel I have a better vocabulary to “sell” the hiring of an experienced professional graphic designer. They use the old adage that a first impression is everything. I would add that you also don’t get a second chance to make a first impression. Visitors to your site make a lot of initial judgments on what the see when they first arrive . You may have the best information to share but if it’s presented poorly it will be ignored or missed. A Graphic Designer will capture the attention of the target audience and present your message to them so they will respond to it.
