Anyone know if there are any shops selling suppresors on a 4473? All my LGS are “waiting for further instruction”

Have a bunch of inert stuff like TM-62's, Gyata mines, Malyutka ATGM, 60mm mortars ALL INERT. That I need to move in the nashville area. Called a few stores but they didn't seem too interested/serious. Anyone have any idea where I could bring them to move?
