Okay, let’s tackle this. So Marcia Tate has skills like garden design, landscape design, horticulture, and sustainability, which are in demand. She has experience as a garden designer & coach, which suggests she can charge a premium. Location is Media, PA, which is a suburban area with a moderate cost of living. According to the Bureau of Labor Statistics, gardeners and landscapers in the PA area can earn around $40,000-$60,000 per year. Considering her expertise and experience, I’d estimate her hourly rate to be around $75, which is on the higher end of the scale.
