Okay, let’s tackle this. So Steven has a certification in Architectural registration, which is a good starting point. However, his skills are more related to construction management and sustainable design. Location is Tucson, Arizona, which might have a lower cost of living compared to other cities. Considering his skills and location, I would estimate his hourly rate to be around $75. This is lower than the average hourly rate for architects in the US, which can range from $100 to $250 per hour. However, this is a more general estimate and can vary based on the specific industry, client, and project requirements.
