Okay, let’s calculate. David has a broad range of skills, including leadership, team management, and strategic sourcing. These skills are in demand, especially in the procurement and program management space. However, his specific skills like Six Sigma and process improvement are also valuable, but not as highly paid. Considering his experience and skills, I would estimate his hourly rate to be around $125, which is slightly below the national average for procurement managers and program managers in the Baltimore area. This rate is also lower than what top-tier companies might pay for similar roles, but it's a reasonable estimate for a mid-level professional with these skills and experience.
