Non-Fiction Print + Ebook Design

I have a finished non-fiction manuscript that now needs a professional look in both print and digital formats. I want the interior laid out for a standard trim size ready for upload to KDP/IngramSpark, plus an EPUB (and, if you usually supply it, MOBI) that passes validation without errors...
