Okay, let’s tackle this. So Ken Elmer has 39 years of experience in carpentry and design, which is a long time. Typically, experienced professionals in the construction industry, especially those with a strong background in design, can command higher rates. However, considering his role as a solar power consultant, which might be less technical than traditional carpentry or design, I’ll adjust downwards. A more suitable estimate would be in the range of $50-$100 per hour, considering his experience and education. Let’s round down to $75.
