Okay, so Pat Miller has 45 years of experience in residential design, which is a long time. Typically, experienced designers in this field can charge higher rates. However, without specific industry benchmarks or location-based data, it's challenging to estimate a precise rate. Considering her extensive experience, let's assume a rate on the lower end of the scale. Residential designers with similar experience might charge around $75-$150 per hour. Given her 45 years of experience, I'll estimate around $75 per hour, which is a relatively conservative estimate.
