Add functionality to existing iOS and Adroid GPS mobile app

We need some changes done to an existing mobile app that is currently live on the App Store and Google play. This app is a geo location and GPS map plotting application and we need one person that is knowledgeable with BOTH Android and iOS mobile development to help integrate the same features into both versions. Changes we are looking to make to the app include:

Changing push notifications

Connecting gps points on a map (making trails)

Color scheme and slight design change to existing versions

Taking away some features like (following users, gps pin creation logs, filters for sorting pins)

Looking for someone that can complete these tasks and provide support to any future changes/ edits to the app going forward if needed.
