Cartoon Animal Digital Coloring

I have a collection of black-and-white animal illustrations that now need lively, cartoon-style color treatment. Everything will be done digitally, so please be comfortable working in Photoshop, Procreate, Clip Studio Paint, or a comparable tool that supports layered files... (Budget: $10 - $30 USD, Jobs: Adobe Photoshop, Caricature & Cartoons, Clip Studio Paint, Digital Art, Illustration, Illustrator, Photoshop, Procreate)
