Need Xamarin expert for a small task (Android)

I have purchased Xamarin source code from CodeCanyon: [login to view URL] I would like you to make minor changes, such as changing the theme color, updating branding, configuring settings, integrating AdMob, and setting up push notifications. Please bid only if you have experience with these tasks. In your proposal, kindly mention at the top, "Xamarin expert," so that I can easily identify relevant bids and filter out random or automated ones. I am specifically looking for experts in Xamarin, Android, AdMob, notifications, and those who have previously worked with this code. Thank you.
