I am going to see if anyone locally can drill the crank
"Danger, Will Robinson!" Unless somebody has a lot of experience doing the drilling, they're just about guaranteed to ruin a couple of cranks getting the hang of it. It's going to be a LONG hole at an oddball angle that has to come out exactly right on the first try. Then they've got to do it five more times, with a zero margin for error.
I'd go with the place that's been successful, even if it involves some shipping cost rather than rolling the dice with somebody who "thinks" they can do it!
