I would hate to have to go to a collections agency.  

I'm not in this to collect pennies. 4) I have a youtube channel with over 20k subscribers and mailing list built over years with 30k+ subscribers that buy my books, content, etc.

You have to give notice of an increase, 30-60 days before you can collect it  I would do it immediately and you can collect in Dec or Jan.
