Okay, let’s tackle this. So Mark H. has 15+ years of experience in IT management, which is a significant amount of time. His education, including an MBA and a Bachelor's degree in Computer Science, adds value. IT professionals with his level of experience, especially in IT management, typically charge higher rates. According to various sources, IT managers with similar experience can charge between $100-$200 per hour. Considering his education and experience, I’ll estimate his rate to be around $125 per hour, which is slightly below the average range but still reflective of his qualifications.
