How to improve render time and render farm recommendation?

I’m planning to render 5 10 sec animation of different interior spaces within the project. I wonder for this type of scene (denoised). What can I do on my render setting to reduce the render time and how much sampling is recommended? the resolution is 1080p.

Which render farm do I use and do I upload each scene individually as a separate file?

Thank you!
