Lucas,
I think it depends on how big you want to go with the final product.
Try talking to a local printer and see what they say.
just google the Name you're looking for and click on "Images" at the top, and you'll get a page full of pics, and there will be a ton of them.
Here I did the work for you:
DD Palmer Images
BJ Palmer Images
Sid Williams Images
The resolution is going to be your stumbling block, but lie a said, a print shop should be able to help with the image, unless you're really handy with photoshop.
