Make pages of 7 e-books

Hi, how are you? I hope you are well.
I'm looking for a designer to enlarge the pages of my ebooks that I have made. The must be done in canva.
I currently have 7 ebooks (each one has about 30 pages and I would like to have 100 pages each).
I have all the texts and the format I would like to follow.
I would send you each texts of each page of the book and it would simply be to make the texts beautiful, including some form, photo etc... As you see fit.
I attach a copy of a few pages so you can see how I would like the format to look like. As you can see it looks professional.
The footer will always be the same and is already designed..
Do you think you could do it? What would be the price?
Thank you very much.
