Okay, let’s tackle this. So Sonja has a mix of event and marketing skills, which are in demand. However, her role seems to be more on the non-profit or charity side, given her experience with fundraising and volunteer management. Location is Middleton, MA, which is a suburban area. Considering her skills and experience, I would estimate her hourly rate to be around $45, which is on the lower end of the spectrum for marketing and event professionals in the US. This rate is also influenced by the fact that she seems to be working in a non-profit or charity sector, where rates tend to be lower than in the private sector.
