Okay, let’s break it down. Mike has 20+ years of experience in marketing, customer service, and sales, which is a solid foundation. His skills in social media, advertising, and public relations are also in demand. However, his experience as an Audio Equipment Technician for 20 years is not directly related to his current role. Considering his education from Excelsior College and his self-employed status, I would estimate his hourly rate to be around $125. This is slightly lower than average for marketing professionals in the US, but his non-traditional background and experience as a writer and book author may justify this rate. Some marketing professionals with similar experience might charge $150-$200 per hour, but Mike's unique blend of skills and experience makes him a more niche player in the market.
