Hi there,
I’ve seen that you have demo content within the site library that supports beaver builer pro and elementor.
My suggestion is to have a closer look at Bold Page Builder:
https://wordpress.org/plugins/bold-page-builder/
It’s one of the few 100% free page builders. Unlike beaver puilder and elementor there is no pro version that you’d have to pay for.
Do you have any experience with this builder and it’s compatibility to generate press? I used it once or twice and think it’s quite good.
