Have you ever driven somewhere and got lost? Come on, I know you have. What do you do when you are lost? A few options: go to a gas station, call a friend or be an alpha male and try to figure it out. I think an amazing, scalable and profitable service would be this:
1- Get a free 1-800 # from Ether, where you can charge people to call you.
2- Hire a few high school interns for the summer at $10 hour.
3- Market a service where people can call the 1-800 # when they are lost and the Interns will use Google Maps to talk the lost driver to their destination.
You can do this idea and when you make it rich just buy me a burrito:)
