Competition INTO Community

I’d like to add a scoreboard, similar to the one used in the NHL (see the image above).

My goal:
Create a competition between two member, with a live scoreboard like the example.

I plan to launch Season 1, which will include a leaderboard and a team viewer (as shown in the picture).

During the competition, each member will be allowed to vote only once for their favorite performance.

Since this will be a competition between artists, I need to figure out the best way to set up and manage the system.
