Okay, let’s tackle this. So Barbara has 24 years of experience in events, which is a long time. However, her experience is mostly in wedding planning, which is a niche market. Location is Rock Hill, SC, which is a smaller city. According to national averages, wedding planners in the US can charge between $50-$150 per hour. Considering her experience, I'll estimate a lower rate. Maybe around $75 per hour, which is at the lower end of the scale. Some wedding planners with less experience might charge this rate, but Barbara's 24 years of experience suggest she could charge more. However, her niche expertise might limit her earning potential.
