1.5m is quite big for hedging plants. Go to a good nursery rather than a garden centre as there will be a big difference in price. Don't know where you are but Buckingham Nurseries are very good. Otherwise plenty of grower nurseries throughout UK
What about Lavender... B&Q do packs of it for hedging...It's evergreen and you get scent and flowers in the summer.. I've got some, and I'm very happy with it..
If you are looking for this as a wind-break for the vineyard then choose a plant that will allow a certain amount of air through as a total barrier will be no good.
Try a specialist shrub nursery for hedging plants. Just stick hedging plants into google and you will find loads.
