Coloring book for adults (ex mandalas) and for kids (animals, truck)

Please carefully read this post.
Do not apply/place an offer if not matching the following requirements.

This is NOT a one-time job request. This could be the beginning of a long term job collaboration.
I am posting this request because I would like to find a trusted Graphic designer / Illustrator to work with regularly.


The person I would like to work with has to be: honest, skilled, professional, precise and reliable during the job period.

The activity will be divided into two niches:
- coloring books for adults (mandalas, animals, abstract objects)
- coloring books for kids

The number of figures for each project will vary, from a minimum of 25 to a maximum of 60. The dimensions of the figures are for books measuring 5x11 inches and must be original (not taken for example by shutterstock).
The theme of the book will be specified by me for each book I order
