YA book cover art

I have completed my polished manuscript for a YA novel, dedicated to my three children and dog. I can share a multitude of details with the right artist, but I am looking for someone to draw cover art for it to start, and several black and white sketches to scatter throughout the book in March when I get my work bonus :-) I can provide pictures for reference, but I would love all three children and my dog character on the cover. Not sure about background setting, but I can provide a novel overview and am open to suggestions.
