Okay, let’s tackle this. So Zain has 30 years of experience in interior design, which is a long time. His experience in high-end curtains, blinds, and upholstery is also valuable. He’s working in Cape Town, which is a city with a relatively high cost of living. Considering his experience and location, I would estimate his hourly rate to be around $150. This is a rough estimate, as it depends on various factors like the specific services he offers, the competition in the market, and the level of expertise required. However, based on general industry benchmarks, $150 per hour seems reasonable for a seasoned interior designer with his level of experience and expertise.
