Okay, let’s tackle this. So John has a diverse set of skills, but no specific experience in a single field that commands high rates. He’s an entrepreneur with 13 years of experience, which is respectable, but not unusually long. His skills like avionics, telecommunications, and computer security are in demand, but not typically high-paying. Location is Darien, GA, which is not a major hub for these industries. Considering his experience, skills, and location, I’d estimate his rate around $125 per hour, which is on the lower side but reasonable for a generalist with his background.
