Fairy tales for children | worldwide - collection

My project is to create a collection of original fairy tales for children. Main guidelines are:
1. i would like to collect fairy tales from all over the world: the tales has to be very tipical/original of specific country (es Africa in general or if possible also specific region of Africa). Real tales narrate to children in that region would be preferred
2. I'll collaborate with many writers, hailing from all over the world: i'll ask each writer to write 5 tales of its own hometown
3. The format of each tale is an E-book in PDF + Word format. The lenght should be 20 pages for tale, including simple and funny graphics to help visualize the story. The ebook should be delivered in final format (completed with a cover with specific graphics for each tale)
4. The format that i'm searching for is ghostwriting

attached you can find an example of final product that i'm searching for
Based on the feedback of this application i ll choose one writer for each country

The budget proposed refers to each Ebook (country depends on the writer) with 5 fairy tales 20 pag each (total 100 pg including illustrations)

Thanks for your attention :)
