If someone else is doing it, I would consider time, availability and shipping charges to be an issue.
Don't know where you are in illinois, but mx-tech is maybe close? They've done mine before. Worked fine.
Everything is easy if you know how to do it. Rebuilding a shock isn't 'hard' (I say conclusively having watched it done once ;) ). That's not to say knowledge isn't required.
Is that mark on the shaft a problem?
How do you keep air out of the assy on put-together?
Is your bladder shot, or just deformed some?
How do you fix THAT (the deformed part)?
What fluid do you use?
Going to change the shim stack?
To what?
And, yes...who's going to put the gas back into the bladder?
Not insurmountable questions, but questions nonetheless.
My last shock service I chose to drive an hour up the road, spend 1/2 hour watching it being done and chatting with a knowledgeable tuner, put it back in same day.
