Do I need SSL and a checkout system to use Protected Content

hmmm. You guys have been very patient with me. It seems I have another issue I have created. You guys have been kind enough to make Protected Content available to me, but I progress through the setup, it seems that I am supposed to already have a shopping cart or some kind of checkout process to use Protected Content. With Pay-Per-View, I understood that PayPalExpress would allow me to have them pay without setting up SSL or an onsite checkout process.

As you guys have educated me, it seems that PC is more suited to my needs, but I am stuck at the point of setting up payment integration.

What do I need to do?
