Okay, let’s tackle this. So Mark has 41 years of experience, which is a long time. Typically, experience is inversely proportional to rate, but that’s not always the case. In some industries, like tech, experienced professionals can command high rates. However, in this case, Mark’s experience is in a non-tech field, and his skills are not particularly in demand. Location is also a factor; the Greater Evansville Area might have a lower cost of living, which could impact rates. Considering these factors, I’m estimating a very low rate of $40 per hour. This is a very rough estimate and should be taken as a rough order of magnitude.
