What sort of stone should I use for a dry stack retaining wall and how much would that cost? - stacked retaining wall

I'd build a wall to dry stack stone. In fact, between 2 walls ... A 3 m, a 2 meters long and 50 meters. I do not know what kind of stone that we have to look or how much it would cost to the cornerstone. Love to help.
