Obviously cost depends on distance from house, depth of pipe, whether you are digging a new trench or digging in the presumably much easier digging of the existing backfilled trench, type of pipe used or required in your area, and interfering utilities or major roots, whether going though/under drives or sidewalks or concrete floor/basement slabs or just from the outside of the foundation, whether underslab basement sections can be elevated to the overlying floor joists (if entry through foundation does not get you right to the shutoff valve location), especially whether excavation has to extend into the street or not (some utility termination points are in-street, some in or at the sidewalk/curb), etc - but below are links to some previous similar questions with ballpark answers which should at least give you an idea and a starting point for evaluating bids.


Normally you would want at least 3 bids for a job like this, because costs can vary widely depending on whether the plumber has a deal with an excavation company to do the digging (or rents a backhoe), if you go with a general contractor who may sub out both the digging and the plumbing work, whether the contractors you call like or want this type of work (some plumbers price it WAYYY up if you don't arrange for the trenching and backfilling yourself, though that can mean more outage time sometimes between completion of digging up the old pipe and the plumber arriving to install the new line), etc.


Recommendation - MANDATE 3 inches or more of sand or pea gravel (better if any risk of the bedding washing out with groundwater) bedding all around it for the pipe. So many contractors just dump the excavated material right back on top of the pipe, which for normal residential service water lines can cause punctures, corrosion points, etc where rocks or organic debris contact it.
