Help to set up 3 different VM images with Catalina, Big Sur and Windows and then populate them with some predefined standard Applications

Hi, For this job, you need a computer with 8gb in ram or more. I am working with a company that builds a forensic tool that analyzes windows and mac disks and finds saved passwords from browsers, passwords and chat from skype, browser history, windows login password, mac login bypass ETC in different browsers. We need to set up VMs with the following OSs - macOS Catalina - macOS Big Sur - Windows 10 we need the VMs set up with some predefined apps and some surf history in the browsers and so on. Its practically about setting up each system and make some structured user data in it such as gmail, facebook logins, skype login and so on and document that. We also need some adult bookmarks and history to try our blacklist filter. We have a google excel with everything that's needed on the VMs Hope this is something you can help us with, you need a computer with 8gb or more in ram to be able and run a VM efficiently. We want to get this going ASAP
