Okay, let’s tackle this. So Diane Alberts has 46 years of experience in a single company, which is extremely rare. Typically, professionals with this level of dedication and longevity in a single role can command higher rates. However, considering her skills are more general and not highly specialized, I’ll need to adjust. Interior designers and owners with her level of experience might average $75-$125 per hour. But since she’s in a smaller market in Rapid City, SD, I’ll estimate lower. Maybe around $50-$75 per hour. However, this is a very rough estimate and should be taken as a very rough guess.
