Okay, so Wolfie Scheun has a mix of technical and management skills, which is a good starting point. His education at Nelson Mandela Metropolitan University suggests some level of technical expertise. However, his skills don't seem to be in high demand or particularly rare. He's in Royal Oak, Michigan, which is not a hub for engineering or tech. Considering these factors, I'd estimate his hourly rate to be on the lower side of the range for engineers in the US. Let's look at some benchmarks: according to Glassdoor, the average hourly rate for an engineer in the US is around $75-$100 per hour. Since Wolfie's skills and experience don't seem to be significantly above average, I'd estimate his rate to be around $75 per hour.
