Hi everyone,
I will soon be seeking work related to graphic design and need to get certain items printed for my portfolio. I'm finding it a bit difficult to tell from a Google search which copy/print shops offer the best quality. Has anyone here had a good experience with any of the copy shops in the area? I'll be doing full-color prints, some of which will be at larger sizes (whatever will be the closest to the US 11x17 inches).

Thanks for any advice you might have!
