Okay, let’s tackle this. So Carolyn Koblin has 28 years of experience in marketing and sales, which is a long time. She has a degree in Advertising from Michigan State University, which is a reputable institution. Skills like marketing strategy, sales, and customer service are in demand. Location is Royal Oak, Michigan, which is a mid-sized city. Marketing professionals with her level of experience, especially in promotional products, typically charge lower rates. Maybe around $50–$100 per hour? But considering her education and experience, maybe higher. Some marketing professionals with similar experience might average $75–$125. So I’ll estimate around $75.
