Okay, let’s tackle this. So Duane has 55 years of experience, which is extremely high. He’s been in the industry since 1969. His role as owner of a company with expertise in multiple areas like lighting control, design, and energy conservation suggests a high level of expertise. He’s not in a traditional corporate setting, but his experience and skills are still valuable. Considering his level of experience, location (Novato, CA), and industry demand, I would estimate his hourly rate to be around $150. This is a conservative estimate, as some experienced professionals in his field could charge higher rates, but $150 seems reasonable for someone with his background and expertise.
