How "hopelessly corroded" is it?
If the manifold is cast iron, that's an easy metal to braise ("bronze-weld") back into shape. Braising is a fairly easy technique to master and is pretty durable. You could do a small repair yourself—buying all the materials you need from a hardware store for ~$50.
A metal shop could braise a small repair for less than an hour's fee. (There may be more modern metal repair techniques for cast iron than braising). Braising would make even more sense if the corrosion is on the
outside surface of the manifold.
