WANTED Flat Field Stone

Looking for some flat field stones for a landscape project. Maybe once used in the foundation of an old farm house, granary, corn crib etc. on your property.

Basically stone foundations that are already exposed and moderately accessible. I know lots of farmers and ranchers have piles of round stones they've picked over the years, but Im specifically looking for flatter stones that were once used for a foundation to repurpose.

Im in Minot and would be travel a little around north central or NW ND for them. We could discuss a small fee if you wanted or your favorite beer or booze. Im not a business just a guy looking to repurpose for my own home projects.
