I just did mine last week.
If you're mechanically inclined and have an aircompressor to remove the axle-nut, I say do it yourself. It's almost the same as removing any other honda axle.
Follow Larry's steps here(

The hard part was the passenger axle has a heat shield with 3 10mm fasteners that you have to remove first.
You then need 2 pry bars at 180 degrees apart to pop both c-clips from the intermediate shaft.
Each boot kit at Acura is $30 each and was back ordered here in SD.
I dropped off the axle at my shop and they rebooted the inboard and outboard joints for $60 labor.
Be sure to take a picture of your camber bolt setting on the LCA.
The total job took me 6 hours.
