Okay, let’s tackle this. So Bill Salter is an Architect with a certification from the State of Florida. Location is Atlanta, Georgia, which is a major city with a strong demand for architects. Skills like mixed-use, residential design, and sustainable design are in demand. However, his certification is from Florida, not Georgia, which might impact his rate. Considering his skills and location, I would estimate his rate to be around $100 per hour, which is on the lower end of the scale for an Architect in the US. This is because his certification is not from Georgia, which might limit his job opportunities and earning potential.
