Okay, let’s calculate. Liz has a mix of teaching and marketing skills, with a degree from UC Berkeley. While her marketing skills are valuable, her teaching experience is more specialized. Considering her skills and education, I'd estimate her hourly rate to be around $120, which is in line with the average rate for marketing professionals with similar skills and experience in San Francisco. This rate is also slightly lower than what I'd expect for a marketing professional with a degree from a top university like UC Berkeley, but her teaching experience keeps it more in line with a general marketing professional.
