1M Sub target on Youtube gaming channel

Hi there, I'm looking at starting a YouTube channel & want to grow it into a large channel. I have been successful running ECommerce businesses in the past & have a strong grasp of digital marketing. I am an Inda-based engineer by trade. The idea behind the channel is that I make stuff, solve gaming problems and show the viewer how I did I and much more gaming-related content. What I'm looking for: Someone to come up with 5-10 research-based ideas for viral YouTube videos/content per week, around solving problems or creating new videos from scratch. The goal is to build the channel to 1M subs + Instagram alongside it. This will be a long-term exciting position.
