Okay, let’s tackle this. So Stephanie Mills has a strong foundation in interior design with various software skills. Location is Miami, Florida, which is a hub for design and architecture. However, without specific industry demand or experience in high-end design, I’ll estimate a lower rate. Interior designers with similar skills in the US can charge around $50–$100 per hour, depending on experience and location. Considering Stephanie’s language skills and software proficiency, I’ll estimate around $75 per hour, which is on the higher end of the range.
