Help Me Find Friends

Hey guys, I'm starting a new project. Starting from square one in overwatch. Level to 25 and start a new comp journey. I wanted to build a following to a stream or just videos and don't know where to start. My stream is all set and ready to go and my test stream was successful. I will do give aways and all sorts of fun stuff once I get a following, but where do I go when twitch is already dominated by mainstreamers?

Any tips?
