Okay, let’s tackle this. So David Diggins has a mix of marketing, social media, and design skills. His location in Boston, MA, is a hub for marketing and advertising. However, his skill set is fairly common in the industry. Considering his skills and location, a rate of $50 per hour seems reasonable, as it's lower than what a senior marketing manager or a designer with extensive experience might charge. This rate is also in line with entry-level or junior positions in the area.
