Looking for suppliers of hedging

I'm trying to find a supplier for a hedge of either Laurel or Privet (Ligustrum Ovalifolium).
The hedge will be between 25 to 49 metres long (depends on what the neighbours agree to).
But I have been asked to try and get shrubs that are already between 1.5 to 2 m high.

I've seen suitable Laurel bushes on the Seagrove and Gardening Express web sites but can't find anyone who can supply the Privet.

Can anyone advise where I can potentially get either of these from at a suitable height please?

Many thanks,
