Hello,
Being a Digital Marketer (having 6yrs of experience) and YouTuber too i can help you getting 1,000 subscribers and 4,000 hrs watch time to start getting Ads for monetization purpose.
We can optimize both the Channel Itself and individual Videos so that more and most qualified users can find us and see our videos.
We will optimize channel and Videos with Proper Keywords, Title, Tags and Description so that we can get better relevancy and can get visibility through Search Engine and within the YouTube (as suggested videos).
Rest assured we know how to get this ... Ping for more discussion and start working on it ..
Have a nice day ahead !
