Create an application for Android

You need to create a mobile Android application for maintaining a shopping list. In general, it will be just a stylized note editor, only with minor changes in functionality. I will send the list and other requirements in the form of a short TZ. The general idea in a more customized application list. The application database should have a list of all possible products (which are in the hypermarket of the CIS countries) in order to give hints when entering a word. There should be units of measurement, etc.
The design of the application will be provided, now in development.
In the responses, indicate the estimated cost of creating an application.
