I want 4000 watchtime in my YouTube channel

I am looking for help to achieve a 4000 watchtime goal for my YouTube channel. My channel is focused on gaming, and the average length of my videos is around 10-20 minutes. I am hoping to achieve my goal of 4000 watchtime within a month. The outcome I am looking for is 4000 watchtime within a month. Ideally, I will be able to find someone who has experience in achieving this kind of goal and can provide me with advice and guidance on what’s needed. I'm looking for help from an experienced YouTube expert or marketing team that can help me meet my goal.
