Inquiry about Nestable Saucepan

I am looking for a simple, durable saucepan designed for the institutional market, not for premium retail. The saucepans should have a slightly tapered (nestable) design so that identical sizes can nest inside each other for efficient shipping and storage. I need sizes like 2L, 3L, and 5L. To simplify manufacturing and inventory, I would like all three sizes to share the same lid diameter, with the capacity changing only by increasing the depth. This would allow one lid to fit all three sizes. I also need to discuss handle attachment options. Please provide details and quotation.
