Creative person with education background needed! Create children's activities for Chinese books

Hello! I'm a children's book author of bilingual children's books in Chinese and English. I am looking for a very creative person to help me create engaging children's curriculum, craft ideas and activities for my books so that I can market them to preschool and kindergarten teachers/schools/educators.

More about my business: www.lycheepress.com

I have 20 book titles that I will need your creativity to develop a kid-friendly curriculum and crafts around.

The task requires you to create 2 ENGAGING activities per title (Total of 40 activities) that are age appropriate for ages 3-6 years old. (preschool to kindergarten)

1. 3 well shot photos of each finished activity
2. All printable files needed for the activity (ideally you can use canva so I can edit it if needed)
3. Written instructions and notes for the teacher
4. At least 3 thought-provoking questions for the children that would be introduced by the teacher

Requirements:
Activities must be age appropriate for ages 3-6 years old
The activity must be able to be completed by the child within 20 mins

You'll need to be skilled in Graphic design and writing; if you know Chinese, this is a huge plus. I will provide you with the PDF files of each book so you can read it and build your activity around them.

Here's an example of the type of activities I'm looking for: https://www.teacherspayteachers.com/Store/Maistorybook

I have no idea how to price this task, so feel free to send me an offer and any portfolio or materials that show your creativity and help me make my decision.
