Okay, let’s break it down. Adam has a Master’s in Business Administration (MBA), which suggests he has a solid understanding of business principles. His skills in social media marketing, data analysis, and market research are in demand. As a marketing professional in Boston, he's likely competing with others for clients. Considering his education and skills, I'd estimate his hourly rate to be around $125, which is slightly below the national average for marketing professionals in the US. However, this is a conservative estimate, and his actual rate could be higher depending on his specific experience and client base.
