Okay, let’s tackle this. So Benni has 43 years of experience as a graphic designer, which is extremely long. Typically, experienced graphic designers in Switzerland can charge higher rates due to the high demand for their skills. However, Benni's 43 years of experience is unusually long, so I'll adjust the rate downward. Considering his skills and experience, I'll estimate around $75 per hour, which is a relatively low rate compared to other designers. This is because Benni is a freelancer and has been working for 43 years, which suggests he may not be as in-demand as younger designers. Nevertheless, his experience and skills still warrant a decent hourly rate.
