I want an android app with firebase backend

I want an android app with firebase backend(everything including database, APIs, etc.) the app will have 2 categories and through each different items will be displayed. Each item will have an image, name, and an short note beneath it's name. A user must be redirected to a link by clicking each item (each item, different link). The app must have banner type admob attached, and the user must be able to remove or disable the ad on his app by using an "app purchase". I want to be able to continuously update the contents of the app and AFTER each update I want a notification be sent to the users of the app. For the development of this app, use a rough firebase account and admob account. For the navigation drawer style : "Banner drawer" Note: I expect to be though either through message, screen recorder or screen shots how to replace the rough firebase and admob account with mine and how to update the contents of the app. And also, please place bid if you are proficient with firebase AND "have developed" app for android with admob AND AD REMOVAL FOR THE USER BY "APP PURCHASE" . Kindly if you are not certain that you can fulfill my expectations, do not bid.
