Depends of course on the fit - if new sink extends further down into the opening so it causes dimensional interference with existing piping or fitting the disposal in, then can run up quite a bit. Otherwise, with normal sized items AND assuming no modification to the countertop is needed, about $200-300 labor plus maybe $10-50 pipe parts should do it.

Plus the cost of disposer and sink - about $800-150 for decent disposal, normal sinks from about $100-350 typically but can be much more expensive - though you said you were providing them. You did not say anything about providing new faucet/sprayer ?

Another $100-150 total if the existing water shutoff valves and flex tubing to the sink is corroded and needs replacement, which is common in installations over about 25-30 years old. Ditto plus another $100-200 labor and $100 parts if corroded metal piping that will not come apart without breaking so basically everything under the sink has to be replaced.

If countertop has to be modified to fit the sink or new holes have to be cut in it for sprayer or air vent or such, then can run from $50-100 range if easily cut material like laminate that plumber can cut (assuming enough lateral clearance) to several hundred $ if a stone or simulated stone product.

In buying the sink be sure it is properly sized for the opening, or that opening does not have to be opened up to the inside face of the cabinet walls - more clearance all around than that is undermount. And if reusing faucet/spray head, etc be sure the openings in sink are correct spacing and diameter.

And watch the matchup between sink and garbage disposal - it can be tough to mate some brands up because of odd sizes, or you have to buy a special adapter gasket and ring.
