Tinster, you've got to shop that around. That is about 3 times too high for the job. The job shouldn't take longer than 6 hours, tops, for a good tech to do. Even giving him 7 hours, that's still close to $200 per hour!
Maybe you could help by removing the passenger seat and carpeting leaving the drivers seat and follow the pictures on my site to see how far down it goes. Remember, Erik stripped my interior completely when he did my job.
And while you're in there, pull the rear engine cover and replace the rear main seal and have the flywheel resurfaced at a machine shop. That should cost another $50-$80 max.
