Add advertisements to my app made on Vue Framework/Node.js/Java

Hello there, lets start by first introducing ourselves we are an Instagram page named @theanimebaka ! We, are planning on creating an anime streaming service, that uses third party websites to stream them. The code for the app will be obtained from this repository : https://github.com/yukino-app/yukino ! Once, we have the code, we have to implement the following changes to the android app part of it:
1. Change logo and color pallette!
2. Add advertisements (Pop-Ups)
And, once we have our app ready, we will use our Instagram page to promote it and earn some revenue!

What's in it for you? Although, we have to add budget here on freelancer, to post a Job request, but this job wont pay you directly. You shall receive the following:
1. Title of DEVELOPEMENT HEAD OF THE APP
2. 20% of the revenue we make from the advertisements!
Which will soon be lot more than what we can offer now!

So, if you agree with these terms, message me! WE CAN BUILD A TEAM, and Convert this into a HUGE BRAND for ourselves ;]
