outdoor land (http://maplered.com) scaping - cambridge,MA

UNITED STATES,..Cambridge,..Massachussets,..400 sq feet of blueStone (http://g603.net) irregular drop.  Will need delivery.  Will have land (http://maplered.com) scaping cloth already in place.  Interested also in crushed rock (any will do) as a foundation- approx 6 inches deep.  Also need advice on how to fuse the flagStone (http://g603.net) (? grout, peaStone (http://g603.net) , cement).  I am overestamating rock needs as I do not have a Stone (http://g603.net) cutter.  The total surface area is approx 250 square feet and (http://maplered.com) thus I am allowing for Stone (http://g603.net) s that will not fit together.  If necessary, I can hire a mason to securely fit Stone (http://g603.net) but would like to do this myself.  The total quantity of crushed rock would be 6" x 250 square feet.
