Seeking source of salvage/scrap bluestone/slate/Belgian blocks/pavers

Hi, I’m looking for a source for extra bluestone/slate/Belgian blocks/cobblestones/pavers or any other stone odds and ends.  I have a walkway adjacent to my driveway that’s currently dirt and needs some TLC.  We envision a major re-landscaping next summer, so it doesn’t make economic sense to buy any quality, permanent materials (particularly since we haven’t yet planned what we want!), but I’d be happy to put down scraps/salvage pieces for the time being.

Any leads (or better ideas) welcome.  Email to fruitstreetguy AT gmail DOT com

Thanks
