T Shirt Maker

So my Theatre / Theatre Tech class at school wants to make T-shirts that say "Theatre & Tech Class of 2013" on the front, with turquoise shirt and being in black and / or the type of money. Then, on the back, we have our different surnames.
Any website, we can go where we can get it super cheap and still do?
or simply a web site very good and dear, where we can make tees like this, but need not be only on the back, we could put our names on the list?

Thank you!

CustomInk is good. If I remember correctly, you can have different names on the back.
