Okay, let’s tackle this. So Dan Rivers has 37 years of experience as an antiques dealer, which is impressive. However, his skills are more focused on marketing and sales rather than technical expertise. Considering his experience and location (Feeding Hills, MA), I'll look at average rates for marketing professionals in the US. According to data, marketing managers with similar experience can charge around $50-$75 per hour. Since Dan's role is more entrepreneurial and less managerial, I'll estimate his rate on the lower end of this range.
