Okay, let’s tackle this. So Denise has 39 years of experience in the industry, which is impressive. However, her role as an owner of a small business might limit her earning potential compared to a corporate setting. Her skills are in demand, but the rate for interior designers can vary widely depending on location, experience, and industry demand. In the US, entry-level interior designers might start around $40-$50 per hour, while experienced professionals can earn upwards of $100 per hour. Considering Denise’s level of experience and the fact that she is a small business owner, I would estimate her hourly rate to be on the lower end of the spectrum, around $75. However, this is just a rough estimate and actual rates can vary depending on various factors.
