afaik roto rooter is the only place i know that uses fiber optic to see what is causing the back up. im not sure what other route to go.
Did you disconnect the trap? Put a bucket underneath to catch the water first before disconnecting.
You can then get a snake from the hardware store and see if you can push it down the pipe.
