Write the report in word format.
Go to
www.zamzar.com and convert the word file into a pdf file.
Upload the pdf file on your web server.
Create a thank you page. Add a mailing list form on that thank you page.
When people sign up for that mailing list - they get your ebook.
So how it'll work is:
1. People pay $7
a. either you get this money or your affiliate gets it
2. In both the cases, the buyer is forwarded to the thank you page
3. The buyer gives his email address on that thank you page (so now you have a mailing list with whom you can follow up and sell more products)
4. They get your ebook through email
