Okay, let’s tackle this. So Jim Erskine has 24 years of experience as a Managing Director at CCP Gransden, a company that specializes in water treatment and renewable energy. His education from Queen's University Belfast adds a mechanical engineering background. Skills like chemical engineering, water treatment, and renewable energy are in demand. Location is Belfast Metropolitan Area, which is a relatively lower-cost area compared to major cities. Considering his experience, education, and skills, I would estimate his hourly rate to be around $125, which is below the average for a chemical engineer with similar experience in a major city. However, this is still a reasonable estimate given his unique combination of experience and education.
