How to collect email address and provide link to download free e-book

I will be setting up a landing page for a campaign and will direct people to the landing page to collect their email address. This would be in exchange for a free e-book. I researched in Google and found that through Unbounce.com I can set up a landing page and with Mail Chimp I can set up a signup form. Am I on the right track here or is there another way of doing this? Also, once they provide the email address how do I provide a link to download the book? I was not able to find information on this subject. I would like to mention that I have a website and blog, however, I am unclear whether I would I be able to create a signup form and a download link on a blog without the use of a landing page and in an easy way? Please advise. Thanks very much for your kind help.
