Okay, let’s tackle this. So Frank Difeo has a diverse skill set with experience in sales management, new business development, product development, and strategic planning. He also has skills in negotiation, marketing, and manufacturing, which are in demand. Location is Haverhill, Massachusetts, which is a smaller city in the US. Considering his skills and location, I'll estimate his hourly rate to be around $125, which is below average for a business development or sales management professional in the US. This rate is also lower than what someone with similar skills in a larger city like Boston might charge. However, it's still a reasonable estimate based on his experience and skills.
