All the hard stuff is pulling the engine out. Once its on the bench doing the bottom end is easy. I would think shipping overseas will be expensive. I'll be retired next summer, until then I have plenty of side projects. I am curious how much folks would charge you.

For me, if you get to that point you will want to vapor blast everything and install all new bearings. The hardest one is the upper clutch arm which is a small needle bearing way up in the case. Took me a while and some surgery but i got it out. Much less work if all you want are new end seals on the crank.

If its the center crank seal that's bad things get expensive.
