Thank you Ian, I found a couple informative links:
http://www.blackdogsigns.co.uk/presses.php
http://www.rubberstamp.uk.com/EmbossingPresses.php

So, one needs a signage professional to make the seal and a press.
I have too look for both around here. I know people who make signs and stamps, but I am not sure if they make such embossing seals.
