touch screen with printer and with gprs

I want a machine to place in parking lots or event control places, without a payment system, which only controls, and prints the receipt with a GPRS system and touch screen to click on the screen and select the numbers and icons. It can be with android or other system. The touch screen you can choose, one with an average cost and the thermal printing roller, I have the model, the gprs I have the models yes, because it has to be homologated in Brazil. If you have the requirements to develop this project, get in touch.

thankful.
