Let’s be honest: We designers can be difficult to work with. We might come from a controversial company culture, work an unconventional schedule or get impatient whenever our Internet connection is slower than the speed of light. Would you be at ease with a service provider who matches this description?
When talking to potential clients, be aware that many will have never solicited a professional design service and likely have little understanding of the design process itself. Keep in mind, too, that some clients have had a poor experience in the past. For many clients, it can be an anxious jump into the deep unknown, a big financial investment steeped in risk.
