App design creation for presentation ( but we need all raw material for future development)

We would like to design a simple App for presentations, but we want to have all raw material for future app development. But for while is only a design.
But we need to define a visual identity for the Brand Promoov and all this visual identity is impacted in the mobile app.


Please disconsider the colors in the app for light gre and light green

We really would like to use color base on gray and light green, as per the Brand Logo in the presentation about the projects idea

This application will be for the Brazilian market and we need to work with somebody fluent in Portuguese to understand all teh project and all screens explanations that we have in the PPT and excel format.

So the freelancer needs to understand Portuguese to go through the project
