I don't have a specific answer.
I used to schedule automobile repairs for insurance though.
Shop labor rate may vary per region, location.
You can call around and ask what their shop labor rate is.
Find out how many book-hours for the job then multiply that figure times the shop labor rate + miscellaneous parts + disposal + taxes.
You could even go so far as requesting an estimate; though they are not really required to be 100% firm on that, as it is an estimate and often run into "unexpected" add-on costs. (but somehow rarely undercut an estimate)
Make sure they include warranty details on that estimate. Some only warranty parts. Some warranty both parts and labor for the work. Some offer no warranty what-so-ever.
