Looking for a $100-$200 dynasty league, and high buy-in Single Season league

In search of a Dynasty League that has a buy in of around $100 - $200, and preferably on the Yahoo platform (it’s all I know), but willing to learn another!

My only preferred settings :

12 man League
18+ man roster
IR Spots
Half PPR
Live Draft

Also down for a single season high buy-in league.

I’m looking for something similar!
