Cost vary greatly around the country, could be a few thosand, depending on where the ducts are located, access, drywall to be removed and replaced,etc..

Please tell use why it needs to be replaced, as we don't run into this situation often.

As BayAreaAC said, replacing more than a piece or two of damaged or rusty ductwork is very rare. Why would you be doing this ?

Even if an inspection revealed a lot of joint leakage and there are a lot of joints that cannot be sealed from the outside because they are in walls, there are specialty contractors who can clean the ducts, then run a camera and sprayhead system into the ducts from up to about 100 feet away, and spray an expanding epoxy sealant onto each seam to make it airtight.

If you are thinking of replacing existing ductwork because it is undersized for a new HVAC system, a much cheaper solution would be running additional duct from the HVAC system to where you need additional capacity, commonly through an unfinished basement or crawlspace or the attic to avoid much drywall tearout. For this purpose, small flexible duct that looks similar to dryer vent hose is used. (comes in from 2-24 inch diameter, residental upgrades generally use 3-6 inch). In the Source box below is a link to a home show video illustrating this sort of add-on.

Should have mentioned the first time,if the ducts are leaking go here;

It seals ducts like Fix-O-Flat for your car tires, from the inside out,plus it measures the actual leakage as it seals.
