Patina finish on wrought iron furniture

I'm a small wrought iron furniture manufacturer and would like to give my furniture a patina finish. But I do not know how to do it neither do we get it here in the local stores. I powder coat my furniture currently. Can you suggest me how I could patina finish my furniture. Your small advise would be of immense value to me. Thanking you in anticipation.
