The Amazon Whisperer

My revenue will come from selling my app and the price that I sell it for. I believe the next thing that my customers would want is parking reservation. The closest thing I could find on Amazon was this. This will help my app by giving me another revenue driver. It will also improve user experience by creating way for customers to get what they want. Not only will they be able to see available parking, paying customers will be able to reserve them. The reviews on Amazon for the similar product was great. There were only 2 reviews but they both said that it was a reliable service and did what it said it would do.
