Application Financial Advice - open to bidding

I currently have a mobile Android application, called Get Paid to Drive. Basically, the idea of the application is the user turns on the application while he/she drives and gets paid for each mile he/she has driven. What I would like you to do, is think of a way for this application to financially run itself. Therefore think of a way to pay the user and also profit at the same time. All I need is an idea, no coding.
