Okay, let’s break it down. Don Clark has a mix of technical and business skills, which is valuable in project management. His experience with sdlc, sql, and databases shows he can handle technical aspects. Business analysis and requirements analysis skills are also in demand. However, his location in Plainfield, Illinois, is considered a mid-tier market. According to national averages, project managers with similar skills in the Midwest typically charge between $60-$90 per hour. Considering Don's skills and experience, I'll estimate his hourly rate to be around $75, which is slightly above the average for the region.
