create new plugin

[fabio]

I would like to have a custom plugin where private user publishes announcement and the firm that wants to see the content of the pay ad.
the company can also buy pocket wallets where it can scale
here an example where the company can choose the advertisement of interest to buy it to see it https://tawk.link/56517ac8c4f9dae563617825/vc/5ae95c078ad2eddb2a854d69/v/7d525f58378d1f761b4598ea5be327bdf6bd6a4c/Screenshot_1.png

here and how it works already in another site https://www.preventivi.it/acquisto-nominativi

If you can modify the osclasspay plugin or create a custom one for me
