I can fo this, but there will be a little bit different because your project is kind of 3rd party app, not the system app.
I am the individual professional developer in Android platform, and have more than 5 years experience on this platform. I did many projects such as Barcode Scanner,certificate management, GPS tracker, Customized Lock Screen, Social App(integrated email/facebook/twitter) and fancy ToolBar etc.
And the delivery time and price are negotiable.
Thanks!
