Based on Shelley's extensive experience in interior design and related fields, I estimate her hourly rate to be around $125. This is lower than average for a seasoned interior designer, possibly due to her location in Fort Lauderdale, Florida, which may have a lower cost of living compared to other major design hubs. However, her 45 years of experience and diverse skillset suggest she can command a premium rate, potentially higher than $150 per hour. Considering the industry average for interior designers in the United States, a rate of $125 per hour is a reasonable estimate.
