Check out tomme molds. I think they have the shape you're looking for. Although, the ones I have are a bit big for a 2lb cheese, I think. They're about 7.5" in diameter, the cheese might come out a bit thin. When I'm working with 2 gallons of milk I generally use a mold that is 6" in diameter, and is taller than wide, but the cheese comes out wider than tall.
