Okay, let’s calculate. Marcela has 1 experience entry, which is a good starting point. She has a mix of design skills, including space planning, furniture, and visual design. Location is Miami, which is a competitive market. According to national averages, interior designers in the US can charge $50–$100 per hour for basic services. However, considering Marcela's skills and experience, I'll estimate her rate to be on the higher side. Let’s say $100–$150 per hour. However, given the lack of specific experience and the fact that she's just starting out, I'll round down to $125.
