Okay, let’s tackle this. So Joanie has 21 years of experience as an interior designer, which is impressive. She has a degree in Interior Design from a reputable university, which adds to her credibility. Skills like space planning, residential design, and customer service are in demand. Location is Palm Desert, CA, which is a desirable location for designers. According to national averages, interior designers with similar experience and education can charge around $100-$200 per hour. However, considering Joanie’s expertise and reputation, I’ll estimate her rate to be on the higher side. Maybe around $125 per hour, considering the national average and her level of experience.
