Required Plugins Install Needed for Local Host

Hello,

I currently have a website built using another premium theme. My website is currently active and used so I don’t want to switch to the Highend Theme until I know the new site appears as it should (is ready).

I am rebuilding my site using localhost and plan to upload it when it’s ready.

I was able to download and install the Rev Slider from another discussion thread but I still need:

Visual Composer – Live Drag & Drop Page Builder
Essential Grid
LayerSlider WP

I have looked through other discussion threads and done searches online. How can I download these to install on my localhost?

Thank you,
Addie
