Based on Mercedes' skills and experience, I estimate her hourly rate to be around $75. This is a relatively standard rate for a program manager with expertise in leadership, team building, and executive administrative assistance, considering her location in Baltimore, Maryland. Program managers with similar experience and skills in the US can charge between $50-$100 per hour, but Mercedes' strong background in managing projects and teams, as well as her experience in travel management and event planning, justify a slightly higher rate.
