I'm not sure of everyones parts situation. There are a ton of local rebuilders in my area. If there are no rebuilders near you, I would consider shipping a water pump for rebuilding. The positives are that you get to keep a factory stamping number, maybe they can find a cast impeller, or maybe you can get a cast impeller from junk parts.

When I buy a remanufactured part, I like finding a Ford or GM logo on the casting. The large rebuilding places use the cores that are available, mostly returned by AutoZone. They are either factory or aftermaket castings. Aftermaker castings are not made until the factory patent has expired. The castings apply from everything that is rebuilt. Wheel and master cylinders, water pumps, etc..,

Just my 2 cents worth.
