Need children’s book illustrator. Hand sketch, family of alpacas with human qualities

I am looking for an illustrator to create the characters and scenery for a new children’s book series. I’m needing the first book illustrated and characters created and will continue needing future books illustrated using the same characters. I prefer hand sketches with realistic, lifelike scenery and characters. I also like the scenery to have depth. I’m wanting a sample created before hiring to do the whole book. Thank you, and God bless!
