Answer: Unfortunately, junipers do not take that well to pruning. Besides require constant attention, they will eventually deteriorate and need to be replaced. Perhaps you would be better off in the long run using a plant that tolerates pruning well and can be kept at the size and shape you require. An upright yew for instance can be clipped and pruned successfully over a long period of time. Your local professional nursery staff may have other suggestions based on a more detailed understanding of the growing conditions where you want to plant and your overall design goals. I'm sorry I can't be more encouraging about the yews.
