Okay, let’s tackle this. So Marlene has skills like online marketing, social media marketing, and marketing strategy, which are in demand. She's also experienced in event planning and travel management. Location is Boston, MA, which is a hub for tourism and marketing. According to Glassdoor, a marketing manager in Boston can earn around $60,000–$90,000 per year. Let’s assume she’s a freelancer, and her hourly rate is around 25% of that. That would be $15–$22.5 per hour. Considering her skills and experience, I'll estimate around $45 per hour, which is on the higher end of the range.
