Laurel is probably the best option - they can grow 12-18 " easily in a year once established. Therein lies the problem, as they'll need trimmed regularly. They get huge if left unpruned. Anything quick growing will also get big quickly so it's a balance.
A hedge of something like Beech or Hornbeam might be easier to keep as, although not evergreen, they maintain their foliage if kept under about 10 feet. Privet is semi evergreen but needs more clipping.
Do you have a fence there? That may be the best option to start with, then you can plant a mix of shrubs - evergreen and deciduous, and it won't matter quite so much if they take a few years to get to decent size.
