T-Shirt Printing

I figured this would be the best forum to create this topic in. What's printing the shirt is hardware after all.

I'm clueless about printing tshirts. I'm looking for a company that can print high quality images onto a shirt in any spot on the shirt. The sites I've been looking at have only the options of chest and the back. The bottom of the shirt or the shoulder isn't an option. And I am also looking to use multiple colors. If someone can point me in the right direction. That would be great.
