Strategies to Protect a Short PDF E-Book?

I know that piracy is inevitable, so I'm not as much worried about. I just simply do not know what website/app or source to use to create a book that then has a paywall and sends it to my clients. Is anyone using a specific website to create these? I have my social media profiles up and I have a linktree, and I have my book basically finished. But after that Idk what to do.
