Early Slant 6 Rebuild

Hey y’all, it’s getting to be about time to rebuild my slant 6.

I’ve recently developed a leak at the rear main seal, and my mechanic doesn’t think it’s worth having replaced until the engine is rebuilt. A little history on the engine, I know the previous owner who knows the owner before him. Neither of them ever had it rebuilt, and the guy who had it before me (an idiot) probably only ever did one oil change in the 5+ years he had the car. It was in bad shape when I got it, so I’ve known this was coming.

Is this something I could fairly easily do myself or is it something that would be best done by someone with experience?

I live in Georgia, near Atlanta, so if anyone knows someone who does quality work on a /6 around here please let me know.
