Live Streaming app

Hello, I want to have a live broadcast application. An application where broadcasts can be watched on the web interface and the management panel is hosted. I’m leaving a sample application site and application link;
After examining, can you make such an application and how much will it cost?
Will you provide support after purchase?
You can access the sample application site and application from this link:
micous.com
And more so, provide me with sample of your past project.
