An iOS and Android app (Only text and Firebase backend)

I'm looking for a developer, who can help me build an app. Please write: 'MOJN', somewhere in your bid, so I can see, that you are not just an auto-bid - Thanks. The app only consists of text fields and buttons. Some of these are fixed, others can be changed in the backend (Firebase). Let's begin: So, people login by Instagram. It has 3 menu-buttons. - Instascore, contracts, and profile. Instascorer consists of a large button, that leads to a new page. This page only consists of a text field and two buttons, that both lead to weblinks. Contracts show companies profiles. I should be able to add and delete these in the backend. When people click on one, they get to the company's personal page. Here we have some more text fields and three buttons: Write contract, Visit, Contact - Write contract (When this is clicked, I should receive a message, telling me both company and username of the profile, who clicked the button). - Visit is a simple button, that leads to a webpage. - Contact is a phone number. So when people click this, they call the company. I set and change the phone numbers on the backend as well. I should be able to accept the person to write a contract or not. I don't know how, but I hope you do. I think, when I receive the message, as they clicked the 'write contract' button, I can manage it in the backend. When they have been accepted, new text fields will show. So basically a new page will be visible, for members. It has a text field, that I can edit in the backend, but that is different from every user. Then we have the last page: Profile. This consist of a picture (Taken from Instagram, as they log in) and their username, also from Instagram. Then we have some editable text fields. There is also two buttons. Both of these lead to a webpage. Thats it!
