Hey,
Let's have a small discussion before you award this project to anyone.
I have been working on a huge project recently which was built all-around exoplayer. I have a lot of experience with the library now and can do anything with it based on your requirements (HLS streaming, m3u8, mpd, etc).
Let me introduce myself. I am an experienced android developer and have been into Android development for the past 3 years. During this period I have developed over 10 apps and published 5 of them on the play store. Along with that, I have delivered all of my freelancer projects successfully. I have worked on Machine Learning, Rest APIs, game development, databases, firebase, etc under app development and have gained necessary skills.
I can deliver you the re-skinned and improved version of your app easily and can make the exoplayer do anything which is possible for the library.
Let's connect and have a chat regarding this so that I can understand your requirements in detail.
