Install Bitrix24 including required virtual app on Linux machine

We need an experienced server administrator to setup the Bitrix24 on-premise version onto our server.

First you will need to setup the Bitrix Virtual Appliance (BitrixVA)

Then install the Bitrix24 Self-hosted application.

NOTE: We don't need any integration into Bitrix24 at this time, instead only the installation.

The server specification is attached for reference - it is a Linux machine.

IMPORTANT: There is currently a live website running on the server that we cant afford any downtime on, therefore to minimise the risk, we will do a full backup of our website before giving you the full access.

Please can you confirm:

- You have setup the required (BitrixVA) and Bitrix24 application successfully on a Linux system?

- You can do this with minimal risk and downtime?

- You can reinstate the website and database from a backup quickly and efficiently if required.

Thanks
Chris.
