Okay, let’s tackle this. So Sean Spaulding has an MBA from Kellogg, which is a reputable program. He has skills in marketing, investments, business development, and portfolio management, which are in demand. Location is Boston, MA, which is a hub for finance. Considering his education and skills, he could charge a rate similar to other finance professionals in the area. Averages for finance professionals with similar skills and experience in Boston suggest a rate of $150–$250 per hour. However, with his Kellogg degree, he could potentially charge a bit higher, around $200 per hour, especially considering the demand for finance professionals in the Boston area.
