Okay, let's see. Marguerite Carroll has been a CFO at Grand Strand Water & Sewer Authority for over 40 years. That's a long time, so she must have a lot of experience. Her skills include strategic planning, financial reporting, leadership, and things like Sarbanes Oxley Act compliance, which is important in finance roles. She also has a CPA and a Master's in Business Administration from Winthrop University.

Location-wise, she's in Conway, South Carolina. I know that salaries can vary based on location. South Carolina might have a lower cost of living compared to places like New York or San Francisco, so hourly rates there might be a bit lower. But her role as CFO and her extensive experience probably command a higher rate.

Looking at her education, she has a BBA in Accounting and a Master's, plus a CPA. Those certifications usually add to one's earning potential. Her experience spans four decades, which is significant. CFOs typically earn a lot, but since this is an hourly rate, maybe consulting or part-time roles?

I need to compare similar roles. For a CFO with her experience in a mid-sized company, maybe the average hourly rate is around $150-$250. But considering her location, maybe towards the lower end of that range. However, her specialized skills in areas like Sarbanes Oxley and managerial finance might push it higher. Maybe around $200 per hour? Let me check some sources. According to Payscale or Glassdoor, CFO hourly rates can vary widely. For someone with her credentials, even in South Carolina, $200 seems reasonable. Alternatively, if she's consulting, rates could be higher. But given the public sector (Water & Sewer Authority), maybe slightly lower. Hmm. Maybe adjust to $180-$220. I'll settle on $200 as a midpoint.
