need to replace O2 sensor(s) 2005 jetta gls 2.0

you can call around using the yellow pages for prices - get a minimum of 3 quotes if you are going to have a shop do it for you AND REMEMBER that just replacing a sensor is not where the repair ends; you have to find out what caused the sensor to throw a code. It can be a worn-out/burned-up/rusted-up sensor or it could be it was sensing a malfunction that needs to be fixed. Just replacing a sensor alone isn';t enough, that would be like opening a window to clear the smoke to stop the smoke alarm from buzzing while leaving the fire burning.
