i haven't seen any mini silouette cutters before (but i also haven't looked for them specifically). a lot of people on CC swear by this company...

they say on their website that they will custom make cutters so i would email them right away, as the husband makes all of them by hand. you'll probably need to send him a pic of the exact silouette you're needing and hopefully they can take care of it from there.
HTH
Silhouettes of what? That might help us determine if we can think of a suitable cutter.
