Before you get into things, you should either have a "verified" Premier PayPal Account or a "verified" PayPal Business Account. Either account type will allow your customers to pay with a credit card and not be required to have a PayPal Account. A Personal Account won't work as they are intended for people who just like to shop online or need to simply send/receive money from friends or family.
As for including a method of Payment for your page - a Buy Now item button would probably work. See the details here to get started:
