Do you watch This Old House? Last year on the Carlisle project they had a lovely stone wall built. It was expensive though -- I think $30K - 40K for a wall that went across the front of the property.

Also where you're located (near to Burlington) may be you could have Roger Cook who does a lot of the landscaping for TOH work on your project. The work he does on the show seems to be of excellent quality.

These are what I found looking on their web site. I am in the same dilmena. I've gotten a few names by writing down contact information of houses where I see walls/patios being built. I try to take a picture from the street also. This has given me a few names.
