Shopping Cart Help NEEDED

I am trying to make a shopping cart website like this:
http://lolanewyork.com/store.htm
click on clothing, then click on any shirt, i want mine to be just like this, meaning when the customer clicks "add to cart" it goes to a shopping cart.
Can anyone HELP ME???

Can any one help me on what type of shopping cart they used?
Thank you!

It's an html site with Pay Pal buttons. If you have the images that site can be up in about 4 hours.

thanks for the reply robin, but what type of shopping cart is that? can i also get that where i can use Amex, visa, and MC?

Exactly what roban said, they use Pay Pal ( PayPal includes all kind of credit cards)
