Given Douglas's unique experience and skills, it's challenging to estimate an hourly rate. However, considering his extensive experience in various roles, including a 96-year tenure, his skills are likely to be highly valued. Typically, professionals with similar experience and skills in the United States might charge higher rates. Without specific industry benchmarks, it's difficult to provide a precise estimate. However, based on the assumption that his skills are in demand, I'll estimate an hourly rate of $150, which is on the lower end of the scale.
