Okay, let’s tackle this. So Daniel Dettmers has a strong technical background in engineering and HVAC, which are in demand. He also has experience in energy conservation and sustainability, which are crucial in today’s market. Location is Madison, WI, which is not a hub for high-paying industries. However, considering his skills and experience, I’d estimate his rate to be around $125 per hour, which is slightly below the national average for engineers and sustainability experts. This rate is also lower than what I’d expect for someone with a degree from the University of Wisconsin-Madison, but it’s still a competitive rate for this location and industry.
