Where to find the plugins?

Hello there!

We have recently bought your WordPress Theme, and after installing and activating it we had to install some required plugins. We found some of them, but not “Physcode – Visual Composer Addon”, “Travel booking” and “Visual Composer”.
I’ve read posts about WPBakery instead of Visual Composer. However, that seems to costs, and we thought it was included in the theme.

Thanks in advance!
