Clickbank and AWeber Integration plus Sales Page Security

On my website where I sell an e-book and video package, I require Clickbank and Aweber to be integrated as follows: When a customer clicks to purchase the item, they are taken to a Clickbank payment page. 1) During the payment process I would like the customers details (name and email address) to be passed to one of my email marketing lists with Aweber. 2) Once the payment has been processed and customer details sent to my Aweber list, an email should be sent to the customer including the 'thank-you page' link where they can download the items they have purchased. Or automatically re-directed to the download page (whichever is more secure and efficient). 3) Now, the customers name and email address should be in my AWeber mailing list and ready to receive further broadcasts if necessary. 4) I would also like the thank-you page to have increased security so other people cannot access the page (and therefore downloads) by simply knowing the thank-you page URL. In summary, I would like the payment process in Clickbank, integrated with my Aweber account and the download ('thank-you') page to be more secure. If you believe this process can be made more simple than I have explained I would like to receive your advice. Please do not bid on this project if you do not have experience in integrating Shopping Carts with Email Marketing Software.
