Stealthy VM (Sandbox) Setup for Malware Testing

I need an expert in virtualization and cybersecurity to set up a virtual machine (VM) for me. This VM will be used for malware testing, so it needs to be undetectable by the malware. Basically, I need a stealth vm / sandbox environment that will hide the fact we are using a VM and will look appear as a normal computer ever with a very sophisticated malware.

Please note that the specifics of the operating system and virtualization software can be discussed and agreed upon with the selected freelancer.
