Okay, let’s tackle this. So Cathy Smithey has skills in multiple art forms like interior design, painting, and illustration. She has experience as a Designer/Artist at Smithey Decorative Painting. Location is Greenville, Texas, which might influence her rate. Considering her diverse skill set and experience, I’d estimate her hourly rate to be around $75, which is a rough estimate for an artist/designer in the United States. This rate is lower than what a seasoned interior designer or fine artist might charge, but it’s still a reasonable estimate for someone with her skills and experience.
