Growing your channel doesn't happen overnight. many GREAT channels have been posting daily for years and they get stuck at 50K or so. Focus on doing it for the passion and not for the money. Post daily, and focus on the content quality. People will watch your videos if they're recorded on a phone, as long as the content is good enough. Good luck!
Oh and one more thing, find a channel that targets a similar audience and shoot for a collaboration, after your channel gains some momentum and you get a resume set for yourself, of course!
