Paint (Rockland)

Hi. I'm painting an art studio on a budget, and wondering if anyone has a half-gallon or more of latex paint in their garage they might donate? Any light color would be fine - and flat, satin or semi-gloss are all ok. If it has mold, or smells bad, like food that's gone bad, I'm afraid I can't use it. But any usable paint would be so appreciated! I'm flexible about when I come get it. Thanks!!!
