Buddlias are very fast...not evergreen but semi evergreen and have a winter structure. Pittosporum is fast and evergreen and attractive. Green,purple, grey foliage. Hebe salicifolia is evergreen with white, purple and blue flowers. Berberis Darwinii is a prickly dark green evergreen with orange flowers in spring. I find it is pretty quick growing. Viburnums too.....different varieties. Foliage plants like Cotinus royal purple are quick after they are established ...not evergreen. Conifers like junipers and taxus are not as slow as made out and can grow quite large. For quick screening what about miscanthus grasses.....they grow 6 to 8' every year?
Perhaps a mixture of evergreen and deciduous shrubs and grasses could solve your privacy issue Sam
