Okay, let’s tackle this. So Mary has a mix of design skills and business experience. She’s worked in the industry for a while, but the exact duration isn’t specified. The rates for designers in the US can vary widely depending on the location, industry, and level of experience. Since Mary is based in Longboat Key, Florida, which is a relatively affluent area, her rate might be on the higher side. However, without more specific information about her experience and skills, it’s difficult to estimate a precise rate. Let’s assume she’s an entry-to-mid-level designer, which might put her rate around $100 per hour, considering the rates for similar positions in the US.
