Creating/designing teaching materials for primary schools in Canva

Hello, I am looking for a creative freelancer who can create new teaching materials for teachers to use in the classroom every day. You can find examples of good teaching materials here: https://eduki.com/de/suchergebnisse?query=
Nice cover: https://eduki.com/de/material/1004376/subtraktion-1-klasse-mathematik-3-arbeitsblatter
Currently, I would like to have different teaching materials for children in grades 1 to 4 (ages 6-10).
Each material should have a goal. Please let me know in advance exactly what the material you create will be used for, what subject it will be used for and how it will be used.
Each material should be 5-25 pages long with 1 cover page (in a canva.com file).
No copyrights must be infringed (if other resources/licenses other than Canva.com are used, always specify). Only unique content created entirely by you. The material should be translated completely into German, if you want with the help of an AI or a programme. Material must be helpful for teachers and have a meaningful learning impact for children.
I pay:
EUR 1.00 per PDF with 5 pages + 1 cover page
EUR 2.20 per PDF with 10 pages + 1 cover page
EUR 3.60 per PDF with 15 pages + 1 cover page
EUR 5.20 per PDF with 20 pages + 1 cover page
EUR 6.80 per PDF with 25 pages + 1 cover page
I look forward to your reply.
