An Arduino sketch using 5" ITDB02 LCD board

I need you to write a simple arduino sketch like following : I am using an arduino mega + a 5" ITDB02 LCD board + a stepper motor 1- you need to use the library at [login to view URL] and the stepepr library at [login to view URL] , with an arduino mega 2560 R3 board to display 3 buttons with some text on them - button 1 : Text = "+" , Functionality : Allows to increase the value of an integer variable in the sketch (let's call it NB); - button 2 : Text = "-" , Functionality : Allows to decrease the value of the same integer variable; - button 3 : Text = "Go" , Functionality : Starts a stepper motor to do NB complete turns (i.e. NB * 360 °), and then stops Of course clicking the buttons is via touch of ITDB02. When one of the above buttons is clicked, it's displayed iva [login to view URL](..) I already gave you the libraries to use and the sketch is simple, so i expect this won't take more than 2 days to finish and costs should not be more than 30$
