Simple Worldpay XML Direct Integration and 1-click upsell

Avg Bid (USD)
Project Budget (USD)
$30 - $250

Project Description:
Only programmers with payment gateway experience should bid here.

Attached is the diagram and here is what I need:

1) The payment page with https. I have purchased the SSL certificate. Example:
2) The XML integration process. I have the sample PHP code already.
3) The storage of buyer info in DB alongwith CC info (excluding CVV info) but CC info will be encrypted. But it should be decryptable also because we'll bill them later.
4) The one-click upsell button. As buyer info is already stored, he'll just click the button and his CC will be charged. Similar to this:
5) A cronjob at the backed which will bill them every 30 days for 5 cycles unless they cancel their subscription. This is easy because we'll have the join date of member. After every 30 days, the system will send an XML payment request to Worldpay for that member and charge him.

PHP coding with MySql databse.

I just need the coding for this process. I have other designers for everything else.
Coding should be fairly easy.
If you have any questions, do let me know.

Skills required:
PHP, Shopping Carts, SQL, Web Security, XML
