A quote as in the cost of the parts? Or the labor?
The last time I searched the eucalyptus it was super scarce. There was a selection is oak, I recall a few hundred dollars. "Market price" would be the appropriate quote as I don't believe there's a single reliable source.
If you're looking for somebody to do the job for you, I'd check with a local body shop, maybe show them the video. It's literally a 10 minute job, 20 if they need to watch the video first and stop for coffee while walking to their tool box.
