Business Idea for T-shirt

I thought of an idea of selling T-shirts with hilarious pictures and texts.
There are many online sites where they print any design we ask for.
There are couple of sites in America, but they don't ship it all the way to Korea
and it is much cheaper to make it here.
The following is one of the biggest sites for funny shirts
http://www.bustedtees.com/
We could use this sits as design reference and create our own design
and try selling them to handong students.
Instead of making many prints with one design,
if possible we could print different designs for each shirts,
because people, especially Koreans don't like wearing clothes others have.
(not team, club, 단체 shirts)
We could also apply Korean language to T-Shirts.
There are three designers among us, so I thought may be we could think about it together.
