Develop a mobile application with a server part

Postpay! I will definitely pay when you do everything, without advances and prepayments!
A project with long-term Cooperation, Individual tasks/orders will be improved, while we are doing mvp0.
I want to work with one developer, not with a team or studio, since the budget is up to 70 thousand.
The terms of development of this order: 2 weeks (I give a slightly longer period, in case of already unforeseen situations, according to other developers, this project is written for a week).
It is necessary once every 2 days (or once a day, as convenient) but not less often to call and show the result of work, I want to control the process.
There is code for the front and back, which another developer began to write. We can continue.
It is necessary to develop a mobile application in react native. Write the server part in python django. Layouts with description: https://www.figma.com/design/tQbxHdRWy4oh3wlMWkEjWX/Untitled?node-id=0-1&t=Viy5acCrVvpd2QQ8-0
The data must be stored on the server. It will also be necessary to implement a simple site with payment. Or with a generated payment link, this is discussed. Pay using the Yukassa API. Payment will be subscription. You also need an admin panel to manage data on the back (creating a user, making an active subscription or inactive, etc.). In addition to data, the server should also store information about the active subscription and check for the presence of an active subscription. The rest of the details are in PM. The cost of the project is negotiable. You will also need advice on the progress of the project. That is, it is desirable to have experience in implementing such applications and publishing them in the store.
