Cover + 35 drawings for coloring book for kids from 4-8 years old

I need a magnificent cover and 35 drawings of animals/flowers/machinery/farm people. Nice drawings for kids ages 4-8.
They are to be included in a low-content book by drawing, word-search and numbers.

I would like drawings only on the right page and leave the left page blank, so that children can use it for writing and drawing.
To these drawings I add some word-search and the numbers next to the drawings to learn the numbers from 0 to 9.
It would be great to have drawings where in each one there are different numbers (4 chicks, 2 cows, 6 eggs, 1 tractor, ...).
The pages must have the copyright and the drawings that will be made can not be used for other works.
The book will be a total of about 80 pages (including word-search).
The book size must respect Amazon's trim size and margin size (8.5 x 11 inches).

The pages with the drawings must be DETACHABLE and therefore need the dotted line on the left.
To give an idea of what I need, I enclose an example made by myself and competitors.
The cover is indicative, I would like to keep a similar layout but with the addition of the right colors and animals to attract the eye and for this I rely on your professionalism.

For the cover, I would like to have warm colors and lots of animals like the attached example (word-search puzzles), I inserted another example (Animal Coloring Book) as an alternative.
On the cover, the title must appear:
coloring book, word search & numbers
and the word farm (to specify the type of animals).
