Database app - My Garden

We have had an app made which is available in the play store called 'My garden'. This is a database of plants and allows users to add the selected plant to the users 'Garden' add calender events, upload photos and more. Firstly you will need to recreate the app as we do not have the sdk? files only the apk, the images for backgrounds and buttons and the database in excel . We are having issues with older phones not being able to use the app correctly and are receiving crash reports so this will need fixing. We would also like to add the following:- Customers can add to the database descriptions or tips on growing the plants they find. This will require some form of reviewing by us or the ‘community’ before showing to the wider audience. Customers can add new plants and the ‘community’ of users will be able to edit and create information with super users that are allowed to review and accept data before going live. Super users earn the title by adding content to the database which is correct and of good quality which earns points to get them to the super user level. We would also like to be able to geo tag each plant so that we start to build a map of each plants coverage globally (this geo tag could be sent to a website and displayed their rather than the app itself - i have server space and sites to use if needed). The app needs to consider a way of creating some form of income and we are open to ideas! Any questions/ideas please ask.
