Okay, let’s tackle this. So Duane Lakin has a PhD, which adds prestige to his skills. He has expertise in multiple areas like training, executive coaching, and leadership development. These skills are in demand, especially in a location like Peoria, Arizona. Considering his education and skills, he could potentially charge higher rates. Let’s look at some benchmarks. According to the Bureau of Labor Statistics, the median annual salary for management consultants in the Phoenix area is around $80,000. However, coaches and trainers with advanced degrees can charge more. A quick search online shows that executive coaches in the Phoenix area can charge $100-$250 per hour. Considering Duane’s expertise and location, I’d estimate his hourly rate to be around $150-$200. But since I have to choose a single number, I’ll go with $150.
