Sorting the slow speeds (the occasional B misfire) is pretty straightforward. If you can use a screwdriver you can do it yourself. In fact you oculd probably go through and do a gentle CLA too.
The most demanding work is curtain and ribbon work. Having tried it myself succesfully, I wouldnt blame someone for sending the camera off. It's very tricky. But the rest really is pretty simple.
Only thing that complicates it here is the self timer, I beleive theyre more of a challenge to strip out, but i cant imagine its too hard.
I would CLA the black dial as its close to being unuseable. But if you're selling it, surely youre goin to make more on it without the cla; that would at least hold up in the UK. In the meantime, clean that slow escarpement in the red dial (or dont, when do you ever use those speeds anyway?) and off you go!
