Cool business idea that has to do with art/graphic design/fashion?

[King Kong]

really want to start my own business, you know first out of home and then grow...I've been trying to start a successful business for about 2 years now and am striving to come up with the right idea. I really like to draw and love art (cool bold art), I've tried starting a t shirt company but couldn't come up with a good logo/theme and I want to start painting and selling my stuff but I want to paint stuff like mario (the nintendo guy) and I 'm not sure if I can sell that with out getting in trouble. I'm really into fashion as well, so I guess thats why I'm so into this t shirt idea of mine. I don't want to work for anybody, so don't suggest it and I don't want to start a website or work online, thats not my thing. SO HERE's the SCOOP: I WANT TO START A COMPANY THAT HAS TO DO WITH ART/GRAPHIC DESIGN/FASHION.....I LIKE T SHIRTS BUT DON'T HAVE ANY IDEAS FOR A THEME/LOGO (like johnny cupcakes or the hundreds, check out their websites to get what i mean) IF U HAVE AN IDEA FOR T SHIRTS OR ANY OF THE OTHER TOPICS PLEASE HELP ME!
