Tree Roots in Sewer Line... Any Recommendations?

[John Stavropoulos]

Tenant water was getting backed up into shower. Plumbers came out and found sewer pipes were clogged with tree roots. Now I need a new line and am looking at ~12,000. 

Any local (Aurora/Western Suburbs) contractor recommendations who may be able to do it for less?

 A new line is the long-term solution.   Short term Root-X and auguring the line should clear it.
