Layout Free Ebook to give away to small business owners for free

I need an ebook laid out properly: the 3rd in my trilogy (now complete) that I give away free to small business owners as a way of 'giving back' now I'm retired.

(I do free events in Devon and then signpost them to my ebooks).

Can you quote me to make this look really good and clear and professional. I'm happy with the text and images, but I need it laid out so all the headings are in suitable places, textboxes are in sensible places, and it looks really clear, easy to read and professional.

I am also happy with suggestions for extra images or other changes to make it look better.

I can't upload the file as its more than 10Gb : here's the link to it on Google Drive
