Android Studio App Building

Help in building an android app from source code on visual studio xamarin The project is bug free but i require some customizations before the build. There are two applications (the normal app and its standalone messenger) This apps has a full documentation on all the customizations i require, meaning no single line of code is required to be written.. I will supply the custom images to be replaced and will give the custom text to be replaced...any other credential required, i will supply. Below are the customizations required on both: 1. Connection to existing PHP backend domain 2. Change Colors 3. Few Words/Phrase edit in language file 4. CHange walk-through Pages 5. Change welcome page background 6. Integrate Google maps 7. Integrate social logins 8. Integrate AdMob (Google ADS) 9. Integrate Facebook ADS (Facebook Audience Network) 10. Push Notification Install using onesignal After the above are done, I will require you to publish them on the google play store using my developer ID. (All images required for google play store will be supplied by me) All the edits/customizations above have a detailed walkthrough in the documentation There is also an error guide. There is basically no need to write codes at all. If you are looking to charge more than $10- $30, do not bother. This task is just a straightforward task.
