Okay, let’s tackle this. So Doug has 44 years of experience as a contractor/owner, which is extremely long-term. His skills in construction, sustainability, and project management are also in demand. However, his education is in biochemistry, which is not directly related to construction. Location is Oakland, CA, which is a relatively expensive area. Considering his experience, skills, and location, I would estimate his hourly rate to be around $75, which is relatively low compared to other construction professionals. This rate is also lower than the average rate for a contractor/owner in the US, which is around $100-$200 per hour. However, this is a rough estimate and may vary depending on the specific project and client.
