Okay, let’s calculate this. Suzanna has a degree from Virginia Tech, which is a reputable institution. She also has a certification as a Registered Landscape Architect in Pennsylvania, which adds to her credibility. Her skills in landscape architecture, streetscape design, and sustainable design are in demand. However, considering her location in Philadelphia, Pennsylvania, and her level of experience, I would estimate her hourly rate to be around $75, which is on the lower side for a landscape architect with her qualifications. This rate is more suitable for an entry-level or junior landscape architect.
