Okay, so David Buzenberg has a diverse skill set, but his experience in merchandising and retail sales analysis suggests a background in retail. In the Greater Chicago Area, where he is based, the average salary for a merchandising manager is around $60,000. However, considering his additional skills in project management and sales management, I would estimate his hourly rate to be around $75, which is slightly above the average for these roles in the area. This rate is also in line with industry standards for professionals with similar experience and skill sets.
