I used Resort Style Backyards for my backyard.  They do a lot of new homes and take it from just dirt to a backyard oasis.  The contractors were very professional and they have a guaranteed finish date.  I've referred a few people and everyone loves them not including the "friends of clients" discount they passed along to my friends.  Tell them Philip referred you.  Check out  http://ResortStyleBackyards.com to see their pics.  Also the number is  949-306-5347
