Hello,
I'm an experienced Linux/Unix Administrator and very familiar with media streaming tools and protocols, including FFmpeg, Nginx+RTMP, Nimble Streamer, Wowza, H264/H265/RTMP/RTSP/HLS/DASH and more.
So I can install and setup Wowza engine for you according to your needs.
But please note that I can't do this in the range of 20-25 USD because this a special and time consuming job.
Anyway, I hope we can agree on this project.
