Elephants and monkey for a book on EGO in sports

Hi
I am looking for about 35 illustrations for a book on EGO in elite sports - so it’s not a book for kids but I would like the drawings to be very childish (examples attached below; this is typically the style I am looking for) to contrats with the seriousness of the rest of the book.
I have imagined a story with two main characters - one elephant and a monkey - both will have different attitudes in relation to each book section
Thanks for your interest
