Okay, let’s tackle this. So Joe Stewart has experience at the IRS, which is a government agency. Cybersecurity professionals with government experience tend to charge higher rates. The average salary for a cybersecurity professional in the US is around $120,000. However, this is a broad estimate and can vary widely depending on factors like location, industry, and level of experience. Since Joe is based in Lanham, Maryland, which is a relatively high-cost area, I'll adjust the rate downward to $120 per hour. This is still a reasonable estimate considering his experience and skills.
