Okay, let’s tackle this. So Robert Weigle has a strong background in leadership, management, and sales. He’s been working for over 64 years, which is impressive. His experience in managing corporate accounts and major customers for Shell Oil and Shell Chemical adds value. However, his education is in Political Science, not a field directly related to his current skills. Location is Houston, Texas, which is a relatively affordable market. Considering his experience and skills, I would estimate his hourly rate to be around $125, which is on the lower end of the spectrum for executives with similar experience. Some industry benchmarks suggest that executives with his level of experience could charge upwards of $200-$250 per hour. However, given his unique blend of skills and experience, I've settled on $125 as a reasonable estimate.
