Teen marketing Business?

[Rico2201]

Hello, I just need an idea or two, I plan on going to college into marketing and or business admin/management. I'm really into starting my own company after working as a sales associate for about a year now. I've been looking into things like social media networking services, but i feel as if my low amount of experience will prove to be useful, and make it difficult to start. Is there any way I could either specialize in something not requiring licensing. I plan on starting it as an llc for expansion purposes. I'm 16 and my age is irrelevant because I can be mature and professional when I choose to be, unlike my peers. I don't even know if i want it to be internet based. Give me any ideas!!!! I'll do it locally as a start if that is what it takes. Please get back to me asap thanks!
