Wordpress Plugin ( blackhat )

Hello, long story short.. I need a wordpress plugin that u can only get if u have a subscription with the service itself.. The plugin that I need is a convertri plugin which is a website for landing page builder ( drag nd drop ) and I will need that plugin for any cost, if anyone here can help me out, I can pay him for that service. Thank u so much.
