Hi, i can help you with your app, creating the database to have all members, renters and other things, we can divide the project for modules, like your Word document, i will use MySQL and the android app in Android Studio, this will take me like 10 work days, we can talk about the price but i think that 300 USD sound good, because, i make the database, the web services, and the app.
PD. the document dont have module 5
