Okay, let’s tackle this. So Robin has a mix of HR and accounting skills, which is valuable. Her certifications like PHR and SHRM-CP show she’s got the expertise. Location is Baltimore, MD, which is a mid-sized city. HR professionals with her skills and certifications might average $50-$100 per hour. Considering her experience and certifications, I'll estimate around $75 per hour, which is on the lower end of the range. Some HR managers with similar skills might charge $100-$125 per hour, but Robin's not in a high-demand area or a large city, so I'm being conservative.
