Okay, let’s tackle this. So Javier Cassoni has 22 years of experience in interior design, which is a significant amount of time. His expertise in Italian Design and Architectural Design is also in demand. As a CEO of his own company, Cassoni has likely developed strong sales skills. Location is Miami, Florida, which is a hub for design and architecture. However, I couldn’t find specific salary benchmarks for interior designers in this location. Generally, experienced interior designers can charge between $50-$150 per hour, depending on their expertise and location. Considering Cassoni’s level of experience and expertise, I estimate his hourly rate to be around $150.
