Payment Gateway Integration - 3d secure experience needed!

We need to integrate Chronopay Payment Gateway and 3d secure in our CRE site. The CP Payment Gateway is different from the module for OSC and requires a custom integration with md5 hash.

We need a candidate who has very good experience with payment gateways, ssl, 3d secure, Server settings, PHP/MYSQL, CGI.

Project in parts:

1. Build a custom payment page for our site that works with our admin and inset all variables needed.

All customer details will be stored in our database as normal, but on the payment page customer have to fill out extra details as card number, card holder, expiry date etc. controlled by a javascipt or similar to prevent missing details.
When customer enter the payment page, the First name, Last name. Adress, Zip code, City, Email, Country will be prefilled since they are sent from our site.
Also the shopping cart contents, pcs, amount and total should be displayed.

The Payment page:

The payment page is for a reason so we do not have to store any data in our database only send to Chronopay by “POST” as described in their documentation we provide.

The payment page has to be dynamic to handle accepted and declined transactions. When accepted, (ID=2) display a thank you message, when declined (pageID=3), a sorry message, please try again. If try again, the customer should be redirected to:/ payment page.php? pageID=1.

When a transaction is accepted, our admin has to display this transaction properly as “CCard Processing” or similar so we can see the order in our admin and also know it has been accepted and by credit card.
The successful/accepted transactions/orders will be displayed in admin as all other others.
Payment page will be in 2 lanuages, and with option to add more later.

We provide a custom design/layout for this payment page



2. Integrate 3d secure (previous experience is required).

3. Testing until 100% functional.
