[Looking4] White metal manufacturer

Hi folks!

Can anybody recommend a white metal- costume jewelry manufacturer in
the US?

I’ve landed a project for an organization- and the final pieces are
to be in pewter/ sterling plated. It’s a 2 piece model- so it needs
to be soldered.

I’ve found a few manufactures but would rather go with a recommended
company- there’s a LOT of detail-in the model and I want to make
sure of getting quality reproductions

Thanks for all replies!
