Okay, let’s calculate this. Julie has skills in interior design, architectural drawings, and renovation. She has a degree from the University of California, Davis, which is a reputable institution. Location is Woodacre, California, which is in the San Francisco Bay Area. Design professionals with similar skills and experience in the Bay Area might charge higher rates. According to Glassdoor, the average hourly rate for an interior designer in the Bay Area is around $50–$100. However, considering her skills and education, I'll estimate a lower rate. Maybe around $75 per hour?
