Photo processing for photobooks

Photos need to be processed. There are lots of photos from different places. I want to take a photo of a book. I select the photos for the book myself, you need to form them in a photo book, make correction of photos, correct if you need to edit. Generally interested in the final result of a photo book with normal photos and good quality design and printing. The first photo book is about 500 photos.
Interested in the finished photo book its total cost and how it folds.
