Okay, let’s tackle this. So John Zajicek has over 30 years of experience as an architect, which is a significant amount of time. His education from the University of Illinois Urbana-Champaign adds to his credibility. He is licensed in multiple states, which suggests a strong network and client base. Skills like sustainable architecture, green building, and space planning are in demand. Location is Mount Prospect, Illinois, which is a suburban area. Architectural professionals with his level of experience, especially in sustainable design, typically charge higher rates. Maybe around $200–$300 per hour? But considering his extensive experience and education, maybe higher. Some top architects can charge $400–$600. Let’s check averages. Architects with his background might average $250–$350. So I’ll estimate around $275}.
