There are two ways to get metal onto an invitation and they are not the same job. Digital foiling is the everyday route: real metallic film, bonded to the print, registered to the artwork, with no metal die to make, no origination cost and no minimum quantity. That is why we can foil twenty invitations for a private dinner. Traditional die foiling, where a heated metal die presses the foil into the sheet, is the route for very long runs, for the deepest impression, and for foil sitting inside an embossed shape. It takes a few days rather than a day, because the die has to be made first. Embossing on its own is a separate process again, quoted per job. Foil and emboss together, in one hit, is the die route.
