Simple Location Android Application

I'm looking for someone to complete an Android app that I have already started developing. It is a simple app that shouldn't require much effort or time for an experienced android developer

Requirements:
Virtual Items will be scattered at a small area on the map that users can collect by visiting various areas of that location.
Players will collect an "item" that has a given value, which will then be added to a collected item list screen.
From the collected item list screen they can select an item
Once an item has been selected for the collected item screen, it will take them to another screen where they will be able to guess the value using a drop-down box.

There are a small number of other features that will need to be implemented but they are not that significant and so will be provided along with my current source files. I have mockups of the application ready to use.

I need the app developed in a matter of 3 days or so. It's a simple app that I don't believe will take experience developer more than a few hours. I'm currently learning android so just need someone to complete the app I'm developing.

Forgot to mention, THE APP HAS TO BE DEVELOPED IN KOTLIN.

On a very low budget plus 80% of GUI has already been created in Andriod Studio and a requirements document is also available so should be an easy job.
