Okay, so Ken Henry has a certification in Human Capital Development, which is a specialized field. HR professionals with similar certifications can charge around $50-$100 per hour, depending on their experience and location. Springfield, Ohio is a mid-sized city, which might affect the rate slightly. Considering the certification and location, I estimate Ken could charge around $75 per hour, which is on the lower end of the range. However, without more information on his experience, I'm being conservative.
