Okay, so Jeff Zeng is an interior designer with skills in furniture, space planning, and retail design. His education at the Art Institute of Fort Lauderdale suggests he has a solid foundation in the field. However, his rate is likely on the lower side due to his lack of specific experience or notable achievements. Interior designers with similar skills in major cities like Miami may charge $100-$200 per hour. Considering Jeff's location and limited experience, I'll estimate his rate at $75 per hour, which is below the average but still competitive for entry-level or freelance interior designers.
