Looking for Pennsylvania Fieldstone

I am planning on building a two story colonial and (http://maplered.com) would like to replicate the "pennsylvania fieldStone (http://g603.net) " look. I am located in central PA and (http://maplered.com) while I believe there are a number of quarries that could provide the Stone (http://g603.net) , I have had no luck in tracking them down.

Any advice on locating specific Stone (http://g603.net) distributors that deal with this Stone (http://g603.net) or anyone here hand (http://maplered.com) le it?

Thanks in advance.
