You are really looking for a self clinging climber. Montana, Wisteria, Russian Vine, Jasmines, are all non-clinging and will need support - a lot of support all over the wall and wire is expensive. I also think you need to go for an evergreen or for most of the year you will be looking at the bare wall.
Self clinging climbers and evergreens are Hedera (Ivies), some Hydrangea and Virgina Creepers. A mix of an evergreen Ivy and Creeper will look good and not that expenses. Should cover the wall quite quickly as well.
When the self clingers are established you can add the like of Clematis - they can piggy back on them.
