Where can I find rear window stickers to advertise a business?

[Stan]

i am looking for a see through rear window sticker to advertise a business, basically clear except for the writing. and i can't find anything except car wraps. if you could point me in the direction of where i can find a cheap one, i would be grateful.

Looking for one that is:
-customisable (just needs to say business name and phone number)
-removable when its no longer wanted
-not a car wrap
-cheap
-clear
