Stamping Or Spinning

We are looking for a manufacturer to either Spin or Stamp the attached part, there are two different sizes, the one attached is the small one and the total quantities are around 3,500 - the larger one is approx 4" in diameter and the quantity is around 7,000 pcs.  - Just heard that the quantities are higher than what I listed above....

We would be flexible with some of the dimensions, if there is someone that has a standard size metal cup.  We would also like the option of different materials, Carbon Steel (powder coated), Stainless (brushed finish) and Copper.

The design has been changed slightly, to allow for stacking, updated models are attached.
