Blockchain App

Hello, I want to know budget and times for an app that has the ability to register any document in the blockchain. It will be an application where each company will have its access and will know what hash has been saved and to know that those documents have not been manipulated. I thought it could be a public blockchain or a private Hyperledger Fabric. I do not know very well how to connect the documents to the blockchain in the same app. The app could be consulted by this company or give access to other types of people. I want a simple, friendly interface ... Would this be possible?

Android only at this point
