We used a landscape designer and she is very good. Her name is Diane Richard and her business is called Gardenscapes by Diane. Here's her website. http://www.gardenscapesbydiane.com/
My husband did all the planting and grunt work on his own but went with her suggestions of what to plant and such. They'll do the work for you if you want, but of course, it's going to cost quite a bit. Hope this helps.
