A single page Windows Phone 8 App

I need someone to add visual basic code to my Windows Phone 8 App to give it functionality. The code required is as follows :- Display the current(todays) date in a textbox on opening the App as i.e. "Mon 21st". Each time I enter a number into a textbox and touch/click the submit button it displays the number in the next available Textblock. Also when the number is submitted it adds up all of the Textblocks to give me a Grand Total. The number values in each Textblock, I would like to be automatically saved into a [login to view URL] or something similar, so the values are still there if I close the App and reopen it later. A Reset button which clears/resets all the textblocks / [login to view URL] to "0" (Zero Value). I've designed the user interface and can email over the Visual studio 2012 windows phone files if needed. This is an app for me personally but your welcome to sell it if you think you can make money of the idea... I'm a London Black Cab Driver and this App would make my life that little bit easier. Thank you for your time to reading this ad.
