Natalie,
I'm not 100% sure what you mean by "i need it to be in gold".
If you are talking about actually
printing gold ink, you need to create a separate channel to represent the art to print in gold. Choose one of the Pantone golds, but understand that it will
appear rather ungold-like on screen. But it will accurately represent the portion of your art that is to be printed in that color. The actual gold ink used would be selected by you and/or your printer, and it will print properly.
But if you are looking to simulate the metallic appearance, but print in the standard CMYK colors, you need to be a bit of an artist to create the highlights and shadows of the shiny metal. You can do this in Photoshop or Illustrator -- but you should have some tear sheets of, say, jewelry, coins, or other gold objects that you can use to help to simulate the effect.
