Looking for a theme/plugin for writers, to pay for articles

I am looking for a theme or a plugin that would allow writers to write articles.
The articles are not visible entirely, only a part of the article is visible and then there is a button or something saying “Purchase this article”.
You buy then with PayPal the entire article, which is deleted from the website when it’s bought. And then the article becomes the property of the buyer.

Thoughts, ideas? A sort of articles marketplace…

99% certain you will need that custom built.

Locking full access to something i.e. the article behind a payment barrier is straight forward enough but to integrate that into a marketplace environment esp. one which removes content when bought is achievable but not something you would find as standard in a stock marketplace
