Cinderella Theme

I`m having a quinceanera party for my niece, and the theme is Cinderella, I need traditions, and ideas please help.. I am also trying to find scroll invitations.. The ones I find in the web are expensive...I live in Georgia, but the party will be in Miami, even if you have information on cheap glass carriages as favors and it`s in another state let me know, the name of the place maybe I can place the order via phone..
