High resolution vector graphic - Tshirt (KC)

I need a graphic for a tee-shirt. ? It will need to be high resolution and vector graphics as the printer prints each color as a layer. I was thinking something like: The top will be text rounded.? The middle will be a demonic looking clown face. ? On each side of him is a gun. ? Like the gangster style tommy gun or a .45 cal handgun. Under the clown is more text, maybe even like the clown head is sitting on it. This will have to look like a current style tee. ? Not an 80's cartoon! Watermarked examples get first look!! Examples of simular work appreciated.
