IBM Model M Steel Bolt Mod

I've been really enjoying the IBM Model M however some of the keys stopped clicking. I think its because of the broken plastic rivets (though I haven't checked). I know there is a fix for that involving steel bolts and nuts but I don't really want to drill holes myself because i am fairly unexperienced when it comes to this kind of stuff. Does anyone here live in Europe (Germany would be perfect) and can do the mod for me (I would pay shipping) or does anyone know anybody who can do the mod for me?
