Okay, let’s calculate this. Carole has a broad range of skills, including marketing, advertising, and graphic design. She also has an advanced certification from Harvard, which adds value. However, her skills don’t seem to be in high demand in Watertown, MA. According to national averages, marketing professionals with similar skills can charge $50–$100 per hour. Considering her certification, maybe around $75 per hour. However, this is a relatively low estimate, and her actual rate may be higher. Let’s assume she’s just starting out or looking to supplement her income, which would bring the rate down.
