Okay, let’s tackle this. So Marie Ennis has experience as a Garden Designer, which is a role that requires both creative and technical skills. Her education in Ornamental Horticulture and landscape design from Temple University also adds value. Skills like landscape design, horticulture, and garden design are in demand, especially in the Philadelphia area. However, considering the local market and her level of experience, I would estimate her hourly rate to be on the lower side. A more experienced landscape designer in the area might charge $100-$150 per hour. However, Marie's skills and education suggest a rate of $75 per hour, which is a reasonable estimate for her level of expertise.
