Looking to buy this script. Anyone know where I can find one?

Can't post images so I will have to explain. I am looking to buy a script where when the person clicks the play button, it brings up a content locker saying to log in to use this feature (or something like that).

I already have the landing page so wouldn't mind if someone could just get me the code for the content lock screen. Been looking for this for a while and pretty much all of the sites I've come across use similar stuff to this.

If anyone know, please share. Thanks.

You can just join a CPA/PPD network and you can lock your content from there.
