I don't have anything fancy, but here is what I have been using for our apartment complexes. I usually download/snap a picture of the property sign. I keep it simple and I always write it as if it comes from the property owner/managers. Property managers really like it so far.

If it was for an HOA, where each house/unit was an owner, I would include more information. But for renters, I don't feel the need to give too many details OR contact information!!

Once you have a template for one of these, keep it for future use.

Make sure it's clear with the property manager who is going to do all this and field all the calls. I usually try to educate the property manager an have them do all the notification and fielding questions. Then the manager can contact me if they need to. Also I make sure it's clear the HOA or managment company is paying ONE bill. I have had instances where they refused to do this and I did it all, notifications, fielding about 50 questions, and individual invoicing. My price is now significantly different depending on who does all this leg work.

You may have already covered your bases on this, but I thought it worth mentioning.
