Need native Polish book writer for publishing on Amazon KDP

Looking for a native Polish speaker to write a book 200-300 page. I would like to use the help of someone who will finish this book, prepare it for publication on Amazon KDP and print, and help me publish it on Amazon. the book should be around 200-300 pages. A part of the order will also be the preparation of the cover, but if this is not possible, I will be able to arrange the graphics for the cover separately.
Please bid only native Polish speakers
