Why not get this done with signwriter vinyl as well? Modern computer driven plotter-cutters are so precise nowadays, they can easily cut fine lines and even text characters as small as 12pt. Your signwriter probably already has clip-art files of decorative scrolls and stuff so you don't need to pay for expensive custom design work.
Don't forget, self-adhesive vinyls are also available in mylar metal foils (gold or silver)... I'm not talking about metal flake finish, but foil finish so it looks like chrome or polished gold...
