I want to remove some options and reduce size of signed apk in my android studio java project

I have a social media project. I want to remove some options and dependency in my project because this app debugging size is more than 200 mb and the signed bundle apk is about 140 mb.

I wish to reduce size of the app around 50 to 80 mb. So I want to remove some unwanted options just like

video post
reels,
live
audio and video chat
calling (video and audio)
face filter
meeting rooms
marketplace

and its dependecy and packages ie

DeepAr
Agora
Img.ly
Mapbox

and change admob to facebook native ad

I am planning to spend only 1000 INR in to this project. If you are interested please contact me.
