How Much does a coach cost? What do high ranking players look for in a team/coach?

I am just doing some research to fill my own personal curiosity. I am also not speaking to an LCS or Challenger scene level, but to a frequent online tournament level. How much does a coach generally charge? Does the ranking of the team change the cost? Do Coaches that have a higher rank themselves tend to charge more? Does it differ between team coaching and individual coaching? Are extra staff like analysts, etc, good for the coach/team? Do coaches prefer teams that are set, or being part of the roster building process? What do players generally look for in a team when they search? Or is it usually more of a volunteer basis? What are the main things that a team needs to be successful and grow?

Any coaches, former coaches, Players, or just anyone with the knowledge can answer these questions: Coaching: What does a coach charge to coach a team of each level: Bronze-Silver: Silver-Gold: Gold--plat: Diamond+:

What does a coach charge to coach an individual in each of the rank tiers:

What do analysts or other support staff generally charge:

Players: How frequent do players prefer their team enters a tournament?

Do players prefer a coach or no coach?

Any other bits of information anyone might have in regards to this subject would be welcome and very helpful, thanks :)
