How to generate WP Visual Composer page once and load static html?

Have wordpress page - http://mderevo.ru/. Don't want any dynamic content - want generate it once as static page, to improve page load speed for SEO and so on.

I'm using W3 Cache plugin now, but it minify only css-js files, but visual composer blocks still generating, image lasy load doesnt work, and so on. Any ideas? :)
