Okay, so Peter has a strong educational background from the University of Virginia. He has skills in multiple areas, including landscape architecture, urban planning, and sustainability. However, the rate for landscape architects and urban planners can vary widely depending on factors like location, industry, and level of experience. In Philadelphia, PA, where Peter is based, the average salary for a landscape architect is around $60,000, while for an urban planner, it's around $70,000. Considering Peter's skills and education, I'll estimate his hourly rate to be around $75, which is on the lower end of the scale for someone with his expertise and experience. However, this is a rough estimate and may not reflect his actual earning potential.
