Can't you just replace the valve stem (kit), after you turn off the
water meter?

That is a gate valve but he still may be able to rebuild it. If not
then you are unscrewing pipe until you get to the next union. I would
seriously think about cutting it out and replacing as much as you can
with PVC. It is a lot easier to work with and it will never rust like
that did.
One hard and fast rule, always put PVC into metal, never the other
way.
Do Not put a female PVC fitting on a metal pipe. It will crack. Always
use a metal coupler and screw in a PVC male adapter with teflon dope.
