Okay, let’s tackle this. So Rosemary Hall has 52 years of experience in a single role, which is extremely rare. Typically, professionals with her level of experience would be in their 60s or 70s, and have likely moved into more senior or consulting roles. However, her industry is not well-represented in terms of salary data, and her skills are not as in-demand as those in tech or finance. Considering her extensive experience, I would estimate her hourly rate to be on the lower side of the scale. Looking at industry benchmarks, event planners and marketing professionals with similar experience in non-profit or association settings might average $50-$75 per hour. Given her location in Kansas City, MO, I would also consider the cost of living in the area. Let’s assume a 10% premium for the location. Therefore, I estimate her hourly rate to be around $75.
