Okay, let’s tackle this. So Preston has 14 years of experience in auditing and financial management, which is a solid foundation. He has held leadership roles in the Maryland State Department of Education and PSC, which indicates a certain level of expertise. His MBA from The Johns Hopkins University - Carey Business School adds prestige. Skills like General Ledger, Accounting, Auditing, and Financial Reporting are in demand. Location is Baltimore, Maryland, which is a hub for financial services. According to national averages, audit professionals with his level of experience and education typically charge between $100-$200 per hour. Considering his leadership roles and MBA, I’d estimate his rate to be on the higher end of that range, around $125 per hour.
