Need a developer or advice for a tournament system similar to starladder.tv?

Question

WordPress

The question, in fact, is this. Tournaments, be they football, basketball or computer games, require the creation of a system for registration, gridding and promotion during the tournament. Here, advise what is, or who is ready to take on the creation of an analogue?
I know that there are WP plugins, but they are raw and more suitable for publication by 1 person, and not independently registering for a tournament, applying, etc.

Answer 1

Looks interesting. I can do it in Django, for example. But there are many details

Answer 2

Oh, these kibindas are sudden. I wanted to say that there is a lot of things that need to be discussed.
