Okay, let’s tackle this. So Shirley Hammond has 45 years of experience as a Registered Interior Designer. That’s a long time. Location is Decatur, Alabama, which is a smaller market. Industry standards for interior designers in the US typically range from $50 to $150 per hour. Considering her extensive experience, I'll estimate a lower end of the range, around $75 per hour. Some interior designers with similar experience in smaller markets might average $50–$100 per hour. So, I'll stick with $75.
