Okay, let’s tackle this. So Peggy has 38 years of experience in lighting design, which is a significant amount. Her education from the University of Delaware adds some prestige. Skills like lighting design, energy efficiency, and space planning are in demand. However, her role as a Corporate Lighting Designer for a supply company might not command the highest rates. Location is Jessup, Maryland, which is not a major hub for lighting design. Considering her experience and skills, I estimate her hourly rate to be around $125, which is slightly below the national average for lighting designers. Some junior lighting designers might charge this rate, but Peggy’s experience and education suggest she should be able to charge more. Maybe around $150–$200 per hour? But for this estimate, I’ll stick with $125.
