There's no such thing as a CMYK gold.
What you need is a special color which should be marked as 'spot' color in your source file and shaped like the logo and header text. Convert text to outlines and the logo to a single color then apply a pink to all these and make it a 'spot' pink set to 'overprint'.
No, I don't know how to do that in Photoshop, but I'm sure its doable. For flyers going to print with gold on top, better use more print-oriented apps like AI or ID, which can export true-vector, print-ready PDFs.
Then talk to whoever will be printing this 'luxury flyer' and make sure they understand the spot color you've used is supposed to be printed in gold. They will then probably take a bucket of PANTONE 16-0836 TPX Rich Gold or Honey Gold or similar to print your logo on top of your flyer as a separate process.
Yes, these are special metallic colors that come in special cans and have nothing to do with CMYK values.
