I.S.
Although someone else recommended Rocky Mountain Ponds and Waterfalls, I would encourage you to consider others. There is no shortage of landscaping companies around. I had a horrible experience and I believe that from a design perspective it's really mediocre. More importantly, it was a really unpleasant experience. Someone else in my neighborhood used them and I think their front looks worse- it accentuated the negative features of the house (front looks tiny now- looked bigger before--). Good luck.
