Activity booklet for kids for a wedding

We have a booklet template 16 pages (in Illustrator) with a front and book cover already illustrated and we are seeking someone to create puzzles / coloring in pictures for the kids. I need something creative and fun that will keep the kids occupied until the adults get settled with the wedding ceremony.

I am looking to hire a freelancer who has experience with designing activity booklets for children and understands what type of puzzles are suitable for this age group. All copyright permissions must be obtained for the images chosen and any instructions provided for the puzzles must be clear and concise.

We also have a set of images that can be used and already have suggestions for puzzles we are seeking, the inside of the booklet is all black and white
