Convert to Internet Catalogue from a Catalogue design in Coreldraw (16-20 pages)

I have a 16-20 pages catalogue design created in Coreldraw. I want to create a internet usable catalogue. Its page should turn to next page when I click. I donot need any links to be made within the pages just the pages should turn when I click. Aswell the pages could be zoomed to read the matter in detail if required. I want that the format of the file should be as that I could mail it to my clients or place on my website so that my clients could download it themselves from there. Kindly specify the format of files I must send to you for this work becasue I think the coreldraw file will be quite heavy? to send it as attachment.
