iRedMail installation on existing Ubuntu server

I would like to deploy IRedMail (it doesn't have to be iRedMail, any open-source webmail-enabled email server will suffice if you have an alternate suggestion) on a Ubuntu server that is live and is being used for other purposes. That server is running: MariaDB Apache Webmin Observium iRedMail is intended to be installed on a clean install. I am looking for someone to deploy it onto this machine without interfering with any existing services. Ideally, you will configure it so that Apache provides the webmail service so instead of two web servers running, there's a single server with a new virtual host. This is a production server and so direct SSH access won't be provided - you'll be working via AnyDesk/TeamViewer/other. I will take a snapshot of the machine before you start and you'll be given 90 minutes to deploy and demonstrate that all services are still running. A detailed proposal is not required. If you can do this, then state a time that you're able to get started (including GMT+/-)
