Watercolor Illustrations for Toddler's Book

I am looking for an illustrator who works traditionally (help of software is ok, but I'd like the illustrations to look original, authentic and handmade) to illustrate a humorous count to 10 picture book with a great emphasis on facial expressions. I like the illustrations to be fairly realistic and attached an example of what I mean by that. In terms of colours I'd like to create a feel-good mood, a mix of lots of different positive colours. The trim size of the book will be 8.5x11", but I will format the book and add the text, so I literally just need the following illustrations: 4 no/transparent background spot illustrations of main character 1 no/transparent background spot illustration of two characters 1 full background/detailed illustration without bleed/with margin (roughly covering 2/3 of a page) 8 small (3.25x3.5") detailed spot illustrations with lightly coloured background 2 half page full background illustrations without bleed/with margin 4 detailed half page illustrations with lightly coloured background 2 full background/detailed single page illustrations with bleed 2 no/transparent background half page spot illustrations 2 no/transparent background single page illustration 10 no background/transparent small spot illustrations of items counting up from 1 to 10, e.g. one jar of honey, a pair of boots, three keys on a keyring, four crayons etc. all the way up to 10 items The timeframe is as follows: 1 no/transparent background spot illustration (used for front cover) within three weeks all remaining illustrations by the end of October 24
