I'd be happy to share the info.
And the pictures I posted up thread are the finished ones, ready to print. If you want to fill in the blank ones, the font I used for the type writer is Old Newspaper type, from dafont.com. The stamps were made by someone awesome here, I think it was bfd. They're on the front page.
The identity card was modeled after the war time British National Registration cards, modified to fit the wizarding world.
As for Snape's information, it's a bit of a logic puzzle to work out. His location is something I (and many other Snape fans) rather agree on based on the information provided by the books. A really good essay on the subject is
here, using excerpts and memories to suss out the childhood home of Snape, Lily, and Petunia.
The dates I got from here:
sun and moon signs, and I made up the validater's name.
The physical description is a mix - Alan Rickman is 6 foot 1, and I guessed the weight based on how Snape is described. The black eyes and hair are of course notable.
And lastly for the wand info, JKR has used birthday woods in the Celtic calendar for wands of the characters, and Snape's birthday of January 9th would give him a wand made of birch. I chose the core myself, and the only wand we know of with a Thestral tail hair is the Elder Wand. I like to think he's a BAMF and would use the power of it.

wand cores
I think I may be forgetting something..
Oh! His middle name is never stated in the book, but there is a pattern of naming the first born son with the father's middle name (Harry James Potter, William Arthur Weasley, etc), so I went with the standard and used Tobias.
