Create coloring book for kids, need 40 coloring pages

I am looking to hire a freelancer to create a unique coloring book for young kids. This coloring book is meant for children ages 4-8, and should focus on animals as a primary theme and subject matter. I am looking for at least 60pages in the coloring book, to ensure that it provides ample amounts of coloring fun for the kids. If possible, I would also appreciate if the coloring book has different art styles and illustrations for variety. On top of that, I will need the freelancer to provide the artwork and draft of the coloring book content. Ultimately, I am looking for a creative, fun, and engaging coloring book that will amp up the coloring entertainment for young, budding artists. Look at the attached file for inspiration and intention behind this book. Feel free to contact me to discuss the direction of the coloring book, thanks.
