Paypal "Website payments PRO"

Hi,

This has been touched on in another topic but didn't really provide me with enough information.

Our website needs to have Paypal website payments PRO in order to alow customers to pay by card without having a paypal account. One of the conditions of Website payments pro is that you also have express checkout. Obviously express checkout is already installed. Can you provide me with some guidance and how to get started with creating a second payment gateway for website payments pro? It's unexplored territory and knowing what needs to be done would really help.

Thankyou for any guidance you can provide.

Daniel
