Yes
I recently acquired a Meyer optik 50mm f/2.9 trioplan lens. It works fine but there is a bit of dust in the lens and also aperture is slightly sticky sometimes.

I would like to have this serviced i.e. cleaned out. I was wondering if there was anyone who could do this at a reasonable (i.e. cheap) price or should I have a go at this myself.

Also it'd be a bonus if who ever servicing it could convert it from exa mount to m42.

2nd the recommendation for Miles Whitehead - whilst most of the tasks you mention probably are doable at home, they are also relatively easy to mess up.
 
I have converted cameras myself to shoot IR. So I am not against doing it at home if I can find a manual or good set of instructions. But unfortunately I couldn't find much info for this lens. Not that this lens is complicated but I am scared of messing up its 18 blades aperture. Also I have never properly taken apart a lens before.
 
Well if you operate the blades a lot that might cure it...also why don't you try the lens out as usually a bit of dust doesn't affect the result.

Hmmm... I felt the blades would get worst over time than get cured.

Yes I'll continue to use it as it is till I can am confident to fix it or get it fixed at a reasonable price :)
An I mentioned it OP the lens works :D
 
Another recommendation for Miles, he's done a great job on everything I've sent him ranging from a 1950s rangefinder through to modern AF cameras. The only possible problem you'll encounter is that his services are in great demand with professionals and amateurs so you might have to wait a couple of weeks until he's got time to look at it.

I've freed up sticky lenses before with careful application of lighter fluid in the right places but that's only really a temporary solution because it's softening the old grease. The other risk is that if you put too much in, it's possible to leach some grease on to the blades themselves and the only answer to that is a full strip and clean so IMO it's only worth taking the chance with lenses that you can replace for less than a repair would cost.
