Okay, let’s tackle this. So Carolyn has a mix of design and management skills, which is good. However, she lacks specific industry-recognized certifications or a strong online presence. Her skills in Photoshop and Autocad are useful, but not extremely rare. Location is Johnson City, TN, which is a smaller market. Interior designers with similar skills in smaller markets might average $50–$100 per hour. Considering her education from East Tennessee State University, maybe a bit higher. Let’s check averages. Interior designers with similar skills and education might average $75–$125. So I’ll estimate around $75.
