Okay, let’s tackle this. So John-michael Davis has 123 years of experience in sales and account management, which is extremely rare. Typically, sales professionals with this level of experience can charge higher rates. However, considering his location in Springfield, Illinois, and the fact that he has been working since 1901, it's difficult to estimate a rate based on industry standards. I'll consider the fact that he has been working for over a century, which is not common. Assuming he's still active and has adapted to modern sales strategies, I'll estimate his rate to be on the lower end of the spectrum, around $75 per hour, considering his unique experience and location.
