[Skunkworks] Payment Gateways

Hello wonderful people. Have a question for web developers. If one wants to make a site which accepts credit card payments what are the available options one can use. I am working on a joomla site and am very green at this. Have used RS Forms Pro to integrate to Paypal but the owner of the site wants both paypal as well as credit card pay options. I am now looking at virtue mart as an option but would like any other options if you guys have and would like to share. Have a great day! Warm regards, Amarjit Singh Labhuram.
