Depends a lot on individual conditions like how many bends there were in the underfloor area, ease of digging (if not following old line), depth of line, whether street had to be dug up (REALLY raises cost), etc -

but a typical job might cost about $1500 probably (bare minimum) to maybe $3000 for the underslab excavation and pipe replacement, maybe $700 range plus or minus a couple hundred for reconcreting the floor, from as low as $500 to $3000 range for the excavation (with later backfilling) to street depending on ease and depth of digging, whether going through or under drive or sidewalk or under or around large trees, etc, around $1000 probably for the pipe and connections and cleanouts. Additional costs could be from nothing to thousands if plantings had to be relocated or removed and then replanted, if drive or sidewalk had to be replaced, and from $500- thousands sometimes in charges from the sewer utility for the actual connection to the sewer main - plus hundreds a day for traffic control while the street was opened up or being worked in, if in a busy street requiring flagmen.

However, for this size job my gut feeling would be the $5-10,000 range, rough ballpark - less if very shallow (3') burial and no interferences or pricey in-street work, possibly quite a bit higher if in union-controlled cities like NYC or Chicago where billed labor rates can be double what you find in many other parts of the coumtry,, and you see 8-12 man mandated crew sizes to patch a pothole or replace a water main shutoff valve.

If you are looking for "evidence" of overcharging (assuming you are the Rooter Router questioner today) you would have to get an official Engineer's Cost Estimate from an civil engineering firm for probably about $300-400.
