I'll have to ask on the piecemeal on the grids. did you have a price/quantity in mind?
This stuff is all leftovers stuff from my employers businesses. Various cabinet parts (cabinet lights and dimmers). The big lights are from the warehouse - we went to more energy efficient ones. The edge molding was probably for garage or closets of some sort.
The rocks are from my bosses aquarium... that started to leak because the guy that built/installed it didn't put a metal frame in the cabinetry.

And the grids are from our furniture store that's closing this weekend.
Still making custom cabinetry though.
