Unless it's an absolute crap casting, that should be a pretty easy fix.
Whether it's simply an "anneal/push back into shape/clean/chamfer/weld/machine" job
or a "clip/build with weld/machine to shape" job,
it should be a relative cinch.
There's not much feature to deal with at that screw pocket.
Once it's welded and prepped, a plunge with an endmill or tiny boring bar will restore the screw pocket, a drill will restore the screw hole. A quick trip to the surface grinder or flycutter for the back face and it's ready for finish and action.
I'd call it a Time/Material job if it were mine and let the smith have a white card from there.
Looks like easy money for Steve and a sure bet for Greg.
