Okay, let’s tackle this. So Carlos Palau has 83 years of experience in teaching and higher education, which is extremely rare and valuable. His skills in teaching, public speaking, and research are also in demand. However, considering his unique experience span and the fact that he is in San Luis Potosí, Mexico, his rate might be lower than average. I'll look at some rough estimates for educators in Mexico. Maybe around 50-100 pesos per hour? But considering his extensive experience, I'll estimate around 75 USD per hour, which is roughly equivalent to 1,500-2,000 pesos, taking into account the exchange rate.
