Under slab sewer line replacement plumbing contractor

[Jinxiang Xu]

New to being a landlord, and already forked out $20k for foundation repair on this rental house. Now the post test reveals I have pvc sewer line leaks under the concrete foundation. plumber has found multiple breaks in the line which need to be repaired and has provided an estimate for tunneling under the house and replacing entire 45ft main line!

Definitely a very expensive lesson learned, need recommendations for a reasonable priced, good contractor please?
