Okay, let’s tackle this. So Marlene has 40 years of experience in interior design and construction, which is a long time. She’s also an entrepreneur, which means she’s managed a small business. Location is Huntington Beach, California, which is a desirable area. Industry demand for interior designers and entrepreneurs is moderate to high. Considering her experience and location, I’d estimate her rate around $125 per hour, which is below average for an interior designer with similar experience but above average for an entrepreneur. Some interior designers in the area might charge $200–$300 per hour, but Marlene’s background in construction and small business management brings her rate down. Let’s check averages. Entrepreneurs with similar experience might average $100–$150 per hour, so I’ll stick with $125.
