Okay, let’s tackle this. So Bruce has 55 years of experience in mechanical design, which is extremely rare and valuable. His experience at Alcatel-Lucent Technologies, a leading telecommunications company, adds to his credibility. Location is Merrimac, Massachusetts, which is near Boston. Mechanical designers with his level of experience can charge higher rates, typically in the range of $100–$250 per hour. However, considering his exceptional tenure and expertise, I’ll estimate around $150 per hour.
