save your $$ and learn to do it yourself, surely there is someone to lend you the tools, or you could buy them all for the service $$, and have them for next time :wink:
You might want to find a shop to press in the mount, as that is not trivial, nor is this whole task. It can chew up the good part of a day. Most of us keep an extra MM bracket or two with new mounts installed on hand, that saves time. They can be bought at junk yards very cheap.
Be sure to put mount in the correct orientation, I had an 80 yr old friend who has done many, but messed one up recently, and then needed to take apart again and fix (that bites!)
