Okay, let’s calculate this. So Joseph has a strong educational background in computer science, which is a plus. He also has extensive experience in managing and securing computer networks, which is in demand. Location is Irvington, New York, which is a suburb of New York City, a hub for IT and tech. Industry demand for IT professionals with network administration and cybersecurity skills is high. Considering these factors, I estimate an hourly rate of $125, which is below the national average for IT professionals in this field but still competitive for someone with his experience and skills. Some sources suggest that network administrators with similar experience can earn $150-$200 per hour, but I've rounded down to $125 based on the lower end of that range.
