Task to perform with 2 cameras with sound

[avoid 0]

I have the following task to perform:
1: To mount 2 cameras with audio - easy task
2. To be streamed live on the website of the municipality - 
3. To have a calendar on this web page / Embedding scripts , CSS, HTMS and etc....will be done by the site programmers, I am asked for a streaming solution / from which to choose to display recordings from the cameras - such as NVR

Any ideas how to get it done. I have targeted the OBS studio software to stream both cameras to the web host company. Any other better ideas.
