What are we talking, about 4cm x 4cm for the stamps? Larger?
If anyone needs a stamp made up quick, I've used rubberstamps.net a few times in the past. They use a 1000 DPI laser engraver. Small shop, great service, fast turnaround, lots of options.
Also, QR codes don't work well. The problem is the ink - voids and inconsistencies when you stamp will usually confound the computer vision. So if you want a URL, use text.
