Okay, let’s tackle this. So Troy Barnett has a broad set of skills, including SAP, project management, integration, and business analysis. He also has experience in retail and human resources. Location is Baltimore, MD, which is a mid-sized city with a moderate cost of living. Industry demand for SAP professionals is steady, but rates can vary. Considering his skills and experience, I'd estimate his rate to be around $120 per hour, which is slightly below the national average for SAP professionals in the US. This is likely due to his location and the fact that he has a broad skill set, which may make him more versatile but also less specialized in a particular area.
