Okay, let’s tackle this. So David has experience as a facility manager, which is a role that requires organizational and operational skills. His teaching background in ESL also shows he has some experience with communication and language skills. Location is Gaithersburg, Maryland, which is a moderate-cost area. Considering the role and location, I would estimate an hourly rate around $40, which is on the lower end of the spectrum for facility managers in the US. However, this is a relatively entry-level role, so the rate reflects that. Some facility managers with similar experience might charge higher rates, but this is a good starting point.
