Children's Book Illustrations

I have written a chidren's book about a black and white kitten named Kallie. She has a puppy friend Bandit. She lives on a farm on the porch of an old white farmhouse. I am needing three illustrations and a cover for the book. I would like illustrations of Kalliie, a mostly white kitten with large black spots and maybe a spot over one eye and of Bandit, a white puppy with black spots and a brown mask. I need one illustration of a farmhouse porch. I was thinking something like a wooden frame home with a long porch that has a roof supported by tall columns. My idea for a cover would be of Kallie walking through the grass of a field with the farmhouse in the distance.
