Okay, let’s calculate. Art Kent has a broad skill set, including leadership, strategy, and sales. His experience in the Greater Chicago Area, a major hub for business and industry, suggests a competitive market. However, without specific industry benchmarks or a detailed salary history, it's challenging to estimate his exact rate. Generally, executives with similar skills and experience in the Chicago area might charge between $100-$200 per hour. Considering Art's broad skill set and leadership experience, I'll estimate his rate to be around $125 per hour, which is on the higher end of the range.
