It's been a long time coming, but Google's distributed video advice service is finally live. Helpouts is a video chat service with a Google backbone, built on the interface and servers of Hangouts. But this is no mere chat service: it's designed specifically for users to connect with and learn from experts in their respective field. You can access the videos from the web or, naturally, the Android app.
Since you'll be connecting with individuals and companies that are ostensibly experts, you'll have to pay them for their time, either on a minute-by-minute basis or in a session fee.
