Youtube channel monetization expert

I am seeking an experienced professional to assist in fixing my YouTube channel, which was previously monetized but has been demonetized. The channel has stopped updating watch hours, and I need someone who can diagnose the issues and restore functionality. the channel has more than 10k subscribers and over 25k watchhours but on the monetization tab the watch hour is less than 3k . Ideal candidates will have a solid understanding of YouTube policies and best practices for monetization. Please provide examples of previous work with similar issues.
