UI/UX - Mockup/ Design/ Wireframe?

For marketing purposes, we would like to create a demo of the core feature of a future software product. Not sure I need wireframe or clickable demo but ideally I want clickable demo as if developer/ client thinks we have a real product.

Please check the attached screenshot of the core features.

Basically, I want clickable, prototype demo where data is made up.

Show me what do I need and how we can do that?
