Cost of 3D printing

Hey guys, I wanted to get a few hundred iPhone stands printed out as a promotion, but from looking at this site, it seems like this could cost $5 each? I could buy them for like $2-3 bucks online. I was hoping to get these cheaper by doing it myself. I was getting the.stl file from this link: http://www.thingiverse.com/thing:475025 Any thoughts appreciated. Thanks, Dave
