Local Seeded Sand/Rock

Hey y'all, I hope everyone is well. Ill be starting up a new to me 210 gal over the next few weeks (hopefully wet in a few days) and was wondering if anyone could help seed some small pieces of dead rock or rubble that I have? I could also trade a cup of dry sand for a cup of live sand if anyone would be willing. In in the Crandall/Forney area.
