You need to invest real money to promote your channel.1000 in 5 weeks?! Wow, I've been doing it for almost 4 years now, but I only have 117. This "first steps period" you seem to cover is far behind me now, so any ideas on what I could do now? Because I already do all you said above.
Adsense in my opinion is money sink so I would suggest you buy shoutouts or traffic to your videos from facebook/instragram group and pages.
