I recommend the Peterson version of the Goetia btw, closest to the original.
1" is just fine (IMG:

However just getting a jewlery place to do it might be less expensive. The little booths in the mall often have good deals (IMG:

They are manual so that you can get it exact. I also have and work with silver discs, copper, lead etc. etc. Most of my discs that I use and sell are 3" and they seem like the perfect size to me. My silver ones are 2" though and they work just fine. I have also etched seals onto other material that is even smaller then 1", and it works (IMG:

Paper sort of kind of works, but nothing like metal or parchment. What I will often do is call the being with a regular seal, and if we are going to continue to work together, or they deserve a really awesome reward I will make their seal with the appropriate metal, or the metal they preffer. If you haven't done this already, you might want to have the gold disc as a reward for Asmoday after the work is done.
Another option btw, for those who cannot afford $100 or more on gold seals, is to use a disc of wood or another metal and purchase 24K gold leafing and leaf it, I have done that will a few discs and they come out quite beautifully (IMG:
