Okay, let’s tackle this. So Alton Peterson has a mix of design and industry skills, which is good. He’s in Chicago, which is a major city with a high cost of living. Interior designers with similar skills in the US typically charge around $50–$100 per hour. However, considering his experience in the hospitality industry, I’ll estimate a slightly higher rate. Let’s say around $75 per hour, which is a reasonable range for an interior designer with his skills and experience.
