Template for Graphics-Heavy Kids Book

My kids and I make the award-winning kids podcast Cool Facts About Animals. The podcast has been featured in the NY Times and is a globally ranked .5% most popular show.
We are considering branching out into a book. Our vision is graphics heavy, which is beyond out limited capabilities. We are looking to have someone design several pages of templates that we could then put our content into.
We are Patreon funded and have a limited budget, but will pay a minimum of $500, up to $1000 based on the agreed upon end product.
