Custom painting

My project is for a large custom portrait painting. I have a general idea of what I want the painting to look like, but I'm open to creative suggestions from talented artists. This portrait should measure more than 48x48 inches and feature a range of subtle color palettes. I'm looking to work with a reliable artist who can bring my vision to life. It has to be a physical painting not a graphic design.
