[first-name],
Connecting with you after receiving a request to setup some time to see a demo. Left you a VM, and understand that this maybe a better way to get a hold of you.
Certainly want to schedule some time with you, looking to gather some more information to make the meeting most beneficial to you and your time. Could you tell me a little more about the project and goal behind it?
Feel free to respond to in the way that is easiest for you.
Cheers,
[your-name]
