How can I start my own streetwear brand?

I have a lot of ideas in my head and designs in illustrator, but I don't know where to start. I know about spreadshirt and springtee, but I want quality shirts and I also want tags on the shirts. And if someone could also show me where I can put designs on bombers and shit like that it'd be dope via /r/streetwear http://ift.tt/2iiIMjV
