Is it possible to by a (ready-grown) large rhododendron bush?

Does anyone know if you can buy rhododendrons that are already grown to about 1.5m high? I have only seen young ones (approx 50cm high) for sale and I need to buy a tall one quite quickly in order to screen something from my neighbours.

Oh, I would need it to be quite wide too - not just a little bush on top of a long stem. (Can you tell I'm not a gardener. )

Like this?

mega expensive.....nik from park?

Ooh fantastic. Thankyou Jackie - that is just what I am after. (I knew mumsnet would come up trupms. I posted on a couple of gardening websites and the only answers I got there were pants)

And washingnappies I agree it is mega-expensive, but it may save a lot of antagonism and wasted expense, so worth it!!
