The cost and terms of application development for iOS and Android. Problem in the text?

Question

Android

Good evening Habr.
I'm straight to the point. There is one project, let's call it "Funny Hugs". This is free-to-play entertainment, with a donation, of course. Our donut is flexible and the benefits from it are extended over time. You can pay $100 and spend it quickly to get all the benefits right away, or spend it slower to stretch the game with the advantage over a longer period of time. The client can always change his "tariff" on his own - as he wants.
Now all donation management takes place through the site, there is an idea to transfer it to mobile devices for convenience. The main development criteria are fast and easy. Actually, I ask the question because I need data on the required resources for developing an application before offering it to directors.
Here is the application layout:

Below is a list of requirements from the application. Since we are chasing simplicity - for the first version of the application, the functionality should be extremely concise.
I) Login screen with main fields:
1) The application must be able to send login data and let/hide the client. There is no need to create a new account.
2) when you click the "forgot" button - a pop-up with support contacts. The functionality to restore / change the account is not needed.
II) A screen with a list of characters and a slider for changing the tariff:
1) Be able, in accordance with Google's guidelines, to switch between character tabs using swap. Functionality for adding/changing/deleting characters is not needed.
2) The most difficult. Calculate data for the slider. Tariffs are calculated on the basis of a constant amount of money spent by the client - 100 rubles - and the combinations of "benefit" and "time" specified in the application. There are 9 such combinations in total.
The application must be able to receive data from the server about how many benefits the client receives and how much time is left. After the client changes the desired amount of benefit - should recalculate the output of the amount of time remaining.
III) Client data screen
everything is simple here - personal data of the client in read-only mode, "back" and "exit" buttons
By design, we already have most of the graphics, if we can provide design. Only the ability to insert existing pictures is required. The project has a ready-made brand book,
Target Devices:
Anything, but to get started you need:
iOS: iPad Air, iPad Mini Retina
Android: at least basic devices with android 2.3 and above, at resolutions above 720p. Widgets are not needed yet.
Desired answers:
- The code part of this project will take this amount of time, it will cost so much money for the studio and so much for freelancers (we have offices in Moscow and St. Petersburg, so we are waiting for the appropriate prices).
- Testing will take this much.
- Publication in appstores will cost so much, in such and such terms.
Well, in general, I want more comments and advice, I myself am far from being an IT specialist, but the task seems to me a feasible team of 1-3 people in 2 weeks, but I don’t know the pitfalls - I came to you for this knowledge, Habr.
PS: Happy New Year!
