Okay, let’s tackle this. So Peter Leaf has 52 years of experience, which is extremely long. Typically, experienced professionals in the US can charge $100-$250 per hour for similar skills. However, considering his extensive experience and diverse skill set, I would estimate his rate to be on the higher end. Maybe around $150-$200 per hour. But since he has been working for the same company for 52 years, that might not be the best indicator of his market rate. Let’s consider his skills and location. He has skills like architectural drawings, Autocad, and interior design, which are in demand. San Francisco is a hub for design and architecture. So, I would estimate his rate to be around $150 per hour.
