Urgently need a freelancer or to find code for a Android app

I need help creating an app for my sales reps so they can get commision, all i need the app to do is to be able to select which Rep makes the sales on a particular day… so basically the app will have like 6 options on the screen and when a customer comes to buy he/she choose which rep gave them a referal and then at the end of the month i can total the amount of leads each rep gets

Does it have to be an app?

Could you not just create unique urls for each rep and use those to quantify leads generated?

hey Charlie, has to be an app, with a database, there wont be time to find or link individual url, its a store setting so the cashier doesnt have that much time…
