Okay, let’s tackle this. So Martin Yarbrough has experience as a Production Supervisor, which is a mid-level role. The rate for this role can vary based on location, industry, and experience. Lubbock, Texas is a smaller city, which might affect the rate. According to national averages, Production Supervisors with similar experience can earn around $25-$40 per hour. Considering the role and location, I estimate Martin could charge around $25 per hour.
