Not only invest in GPS but train your drivers to learn how to use them AND make sure your dispatch and drivers communicate well. I use taxies a lot in California and I will call the night before i need a ride and give the dispatch my pick up address and drop off address then the next morning the taxi shows up late and has no clue where I need to be dropped off at. Build a good reputation and then worry about links. When your drivers and dispatch do a good job have the drivers pass out a business card then seek out travel review sites and people like me will give a good review.
