Install Engintron + xVarnish together in a new cPanel CloudLinux

Before explaining, we want to be very clear that we're looking for long term providers that are affordable and also very experienced with lots of years working on hosting environtments / very experts in Prestashop in this case. Very hoenest people, if you do this fine we will givbe you more tasks of other projects, since we're an agency and have multiple clients / projects, most of them based in WP Please bid relevant information like your notes about this project or veifying that u're already done this, technical info .... but don't put the typical portfolio, I will ignore your bid. We're getting a new VPS with large resources. We will host large WooCommerce sites and need them to load as highter as possible. So we would need to implement the best optimization possible using something like this: - cPanel (already installed) - CloudLinux (already installed) - Enable OptimumCache - Engintron (nGinx) (we can install it) - Xvarnish - Memcached - PHP-FPM - PHP7 - RAMDISK for nGinx --> [login to view URL] Theorically, this is not possible without tunning, so if you can't build it and u have a lot of experience doing this, u're my man ! We will require also best optimization in the complete stack (MariaDB 10 optimization, PHP-FPM, etc) You shall suggest anything that is worth to implement instead of this combination. We need sites to load amazingly fast. Thanks
