Who would you recommend I contact for supplying me all the cherry, prefinished, for building a ceiling lattice as shown in the pic here?View Image

All would need to be select lumber, and either clear straight all heartwood, clearcoated, or perhaps if we allow some sapwood, it would be first stained with a cherry dye, then clearcoated. 

I might need something like 240 pieces, all 3/4 x 3 x 48, end-cut for exact length match.
