How about Photinia x Fraseri 'Red Robin' (hope I've spelt that correctly from
memory).

It's something that can be pruned to shape to form a hedge. It grows fairly
quickly, but in my experience won't grow too tall, though I'm sure there's
someone who's got a next door neighbour who has one that's a real nuisance
because they never prune it and it's 30 feet high!

All the best with your quest. Let us know what you decide apon in the end.
