Anniversay gift- music box or personalized frame

Hey there,
Has anyone ever ordered a real custom music box. I found many on the internet and even the music box company store but they are require using their tune list and I am trying to put our wedding song in the box- it was Thank you by Led Zeppelin- not a common song. Also, if not that, do you know any place that will etch the words in either a frame or glass plate?

Thanks for the help.
Joe

I love the idea of a music box. What a beautiful gift idea. What site did you find it on?
That actually would be a great shower gift or BM gift too.
