Time estimates for standing up a jitsi server and 'standard' jitsi client services

Hi

I am planning a project to integrate Jitsi into a new application. Our team is unfamiliar with jitsi or webrtc, so it would help a lot if, from a project planning perspective, I could ask this experienced community roughly how many man days we should expect to take:

  1. With our own team who start from no jitsi experience
  2. a subcontracted team who have jitsi experience

Assume the application outcome has to look like Jitsi Meet - but hosted on our AWS servers.

Many thanks in advance
