Regardless of which workshop you use, do the Environmental thing & ask to see their environmental license or certificate if it's not displayed.
This ensures that the workshop is registered & licensed & they are (should be) doing the right thing environmentally.
You can pretty much bet that if a workshop is particular enough to do the right thing in this area, they would also be putting out pretty good work as well.
I persnally wouldn't use the services of a workshop that was dumping used oil in the creek, no matter how good their work was.
And don't laugh at that. Last yr there was a workshop in Moss St (Qld) that was caught with a direct drain pipe from their oil drop pan into the stormwater down pipe.
