Okay, let’s calculate Brenda’s rate. She has a broad set of skills in business development, marketing, and leadership, which are in demand in the start-up ecosystem. Her location in Boston, a hub for start-ups and tech companies, also contributes to her earning potential. Considering her skills and location, I estimate her hourly rate to be around $125, which is below the national average for business development managers but competitive for a start-up professional with a strong marketing background. This rate is also in line with what I've seen for similar professionals in the Boston area.
