Okay, let’s calculate Mark’s potential hourly rate. Considering his skills in manufacturing, mechanical engineering, and product development, he’s likely in demand. In the US, mechanical engineers and manufacturing professionals with similar skills can charge between $50-$100 per hour. However, his experience in management and continuous improvement adds value. Let’s assume a mid-range salary for his role, around $75,000 per year, which translates to approximately $36-$45 per hour. Given the industry demand and his skills, I estimate Mark could charge around $75 per hour, considering the lower end of the scale.
