[HIRED] YouTube Subscriber Cog

I have read and understand the Cogboard Bounty rules

Discord Username: ChristianRauchenwald#1475

Description of Cog
I am looking for a cog that checks if a Discord user is subscribed to a specific YouTube channel and if yes assigns (a) specific role(s) to that user and/or removes (a) role(s).
The cog would need to re-check the subscription status of users in certain intervals.
