Okay, let’s tackle this. So Robert Thompson has skills like landscape architecture, sustainable design, and urban design, which are in demand. He’s based in Pittsburgh, PA, which is a city with a strong focus on sustainability and green spaces. According to the Bureau of Labor Statistics, landscape architects in the US typically earn median salaries around $62,000. However, considering his skills and location, I’d estimate his rate to be around $75 per hour, which is slightly above the national average. This is a reasonable estimate, given his expertise and the value he can bring to clients.
