Okay, let’s calculate this. Rebecca has a mix of customer service, insurance, and training skills. Her certification as a Certified Nursing Assistant (CNA) is a plus, but it's not directly related to her skills. Location is Baltimore, Maryland, which is a mid-sized city with a moderate cost of living. According to national averages, customer service professionals with similar skills can charge around $25-$35 per hour. Insurance professionals might charge more, but Rebecca's certification doesn't suggest she's working in that field. Training professionals can charge around $30-$40 per hour. Considering her skills and location, I'll estimate around $40 per hour.
