I am sorry for this delayed reply to your gardening question. We are transitioning to a new Q&A system and your question was unfortunately lost in the transition. I have discovered it now and hope this reply is not too late to be of help.
To get a shrub that is fairly tall so as to make a good privacy border, and economical I suggest you consider 'Bright N Tight' Cherry Laurel. If drainage is fair to good it will do well and make a dense border. Southern Wax Myrtle is also a good choice but make a wider hedge that is not as tall as the cherry laurel.
Thanks for the question. Please stop in again soon!
