Hey Terry,

Actually I am working on a start-up called MinuteBox.com (http://www.minutebox.com) and we are doing exactly like this. We are based in London.

We want to create a marketplace for people to buy and sell advice via video chat. Therefore, our users can monetise their expertise in small unit of time. The MinuteBox platform allows users to access expert advice in a cost-effective way. On the other hand experts can sell their time directly to users at their own convenience.

This is our demo video: http://vimeo.com/13758599 You can have an idea how we approach this.

We are preparing for the launch and it would be great to get more feedback from you.

Cheers

Josh
