Creating a mobile application

Hello, I am interested in this app.
It is divided into two subtypes or related to each other by type of registration.
Registration.
1. User (card name mail tel )

2. Distributor (card name mail tel )

1- Task. Only upload photos and send 2 (to the distributor)
2- Task . Receive photos from 1(user) and send a message to the user and see his registration card.

1-free
2- payment per month of a certain amount.

I am interested in the cost of such an application.
