A8 Timing belt change

[timshap]

I have a 3.7 QS at 70,000 miles and is due next service shortly. I am planning on keeping the car (which has been great over the past 2 yrs) for a further 2 yrs and wondered if its possible to get an independant to do the job.
Just had front brake pads replaced by a good quality indy and saved a fortune compared to last time by Audi.
Is it wishhful thinking on my part...I`ve heard that the front end of the car has to come off ??? Views appreciated..thanks
