Looking for no money / redraft / online league for 11 year old son

Hi -

My son has played in our family league the past few years, is very active and competitive. Lost the championship last season by only a few points.

He is looking to branch out and find some more competition.

His experience is with a standard league, but could adjust to PPR.

If there is a league that would be a good fit for this scenario, please let me know.
