Okay, let’s tackle this. So Kevin has a mix of writing skills and medical expertise, which is valuable. However, his specific skills don’t seem to be in high demand. Writing is a general skill, and while he’s good at it, it’s not a specialized skill that commands high rates. Considering his location in Greater Philadelphia, which is not a hub for high-paying industries, and his medical background, which is not particularly specialized, I’d estimate his rate to be on the lower side. Maybe around $100 per hour, considering average rates for writers and medical professionals in this region.
