Android and iOS app UI Design

We require a UI Designer for a straight forward mobile app which allows to track sales target achievement. This app is available for devices supporting Android OS 4.2 (Jelly Bean) or later and iOS 6.0 or later.

The design elements needed are:
- 1 Logo to be improved
- 1 Splash Screen
- 1 Sliding Menu bar
- 7 icons
- 4 screens with input boxes and buttons
- 1 screen with 4 graphs & charts
- 3 information boxes

The primary users of this app are high flying sellers from various industries and as such the design should inspire trust and seriousness while being calming, modern, clean and minimalist.

The final deliverable must include the design for multiple screens for both Android (mdpi ,hdpi,xhdpi, xxhdpi) and iOS (Retina and non-retina for iPhone and iPad).

Screenshots, source code, .apk, and other helpful material will be provided to selected designer (who should have experience working with developers).
