Okay, let’s tackle this. So Barbara Stough has 41 years of experience in interior design, which is extremely extensive. Her education from the University of Cincinnati’s DAAP is also a strong indicator of her expertise. Skills like interior design, space planning, and commercial interiors are in demand. Location is Cincinnati, Ohio, which is not a major hub for interior design. However, considering her extensive experience and education, maybe a mid-range rate would be more suitable. Interior designers with similar experience and education typically charge between $75-$150 per hour. Let’s estimate around $125, which is on the higher end but still reasonable considering her level of expertise.
