Okay, let’s tackle this. So Evalyn has 45 years of experience in interior design, construction management, and sustainable design. She’s a leader at Design Era, Inc., which suggests she’s highly skilled and respected. However, her specific skills like bathroom, furniture, and space planning don’t seem to be in high demand. Considering her extensive experience and leadership role, I’d estimate her hourly rate to be around $150. This is a relatively conservative estimate, as top interior designers with similar experience can charge upwards of $250-$300 per hour. However, Evalyn’s specific skillset and industry may not command such high rates.
