Okay, let’s tackle this. So Andrea has skills in accounting, auditing, and financial analysis, which are in demand. She also has experience with the Sarbanes Oxley Act, which is a significant certification. Location is Baltimore, MD, which is a major financial hub. According to the Bureau of Labor Statistics, accountants in the Baltimore area can earn around $50,000–$80,000 per year. Considering her expertise, I'll estimate her hourly rate to be around $75, which is slightly above the national average for accountants with similar skills and experience.
