Okay, let’s break it down. Mary Kaye has a diverse set of skills, but none of them are in high-demand fields like software development or finance. Coaching and writing can be lucrative, but the rates vary widely depending on the industry and location. For a coaching or writing professional in Wellesley Hills, MA, I'd estimate around $75 per hour, which is on the lower end of the spectrum. This is because her skills don’t align with the highest-paying industries, and she lacks experience in high-demand fields. That being said, her teaching and public speaking skills could potentially open up other opportunities, but I'm not factoring those in here. To give you a better idea, here are some rough estimates of hourly rates for similar professionals: $100-$200 for writing, $50-$100 for coaching. So, my estimate of $75 is a bit conservative, but I'm playing it safe given the limited information.
