Okay, let’s tackle this. So Paul Hayton has an impressive 45 years of experience in product design, mostly at Rolls-Royce. That’s a long time to be innovating and implementing new designs. Given his experience and expertise, especially in a prestigious company like Rolls-Royce, I’d estimate his hourly rate to be around $250. This is higher than average for a product designer, considering his extensive experience and the fact that he’s fully retired, which suggests he’s not looking to take on additional work. This rate is also in line with what I’d expect for a senior design expert with a strong track record of innovation.
