Okay, let’s tackle this. So John Lee has skills like R&D, catalysis, and materials science, which are in demand, especially in industries like chemistry and product development. Location is Baton Rouge, Louisiana, which might have a lower cost of living compared to other US cities. Considering his language skills and expertise, I'd estimate his hourly rate to be around $100, which is a reasonable starting point for a chemist with these skills in this location.
