Microsoft has people whose job title is literally "evangelist", which are tasked with engaging with the tech community.

They get paid to produce tech demos, give talks, engage with the community, alpha and beta test the latest and greatest tech, etc...

If you connect with people who are Microsoft MVPs, they can probably put you in touch with them. I think engaging with some through Twitter would be the way to go.
