I want to bring colour to my existing logo - gold and green!

I'm looking to bring colour and a tag line to my existing logo! I've had my logo since 2013 and it needs revitalising. I'd like to have the writing in gold to represent the wonderful people & products I work with and green in the background to represent the land, where lots of our food comes from!

I'd love your help in bringing my logo to life for my website, social media, headed paper and business cards.
