Selling on the 'Net question

This may not be the place for a question like this, but here goes.

I'd like to sell an ebook and then on the "Thank you" page offer another book for a ONE TIME offer. Then, each buyer gets a chance to become an affiliate for 100% commision.

How can this be done?

Basically, you are creating a viral offer and making the front end sale and then a few back-end sales, while building a list.

Warmly,
