Okay, let’s tackle this. So Robert Soldo has 14 years of experience in interior design, which is a solid foundation. His skills in space planning, submittals, and LEED AP are highly valued in the industry. He’s worked at two established firms, Robert Soldo Design and RTKL, which suggests a certain level of expertise. His education from Tulane University, a reputable architecture program, adds to his credibility. Considering his experience, skills, and education, I would estimate his hourly rate to be around $125. This is slightly below the national average for interior designers, but it's also lower than what someone with more extensive experience or a stronger portfolio might command. However, given his focus on sustainable design and his experience working in the Miami market, I think this rate is reasonable.
