[Armageddon] Why would NASA hire some random drillers instead of a giant corporation?

They are literally trusting the fate of the world in some dude with poor impulse control and his band of misfits.

Wasn't Exxon or Shell available? Or some other giant corporation with drilling operations all over the world.

They could have provided a drilling machine where every last bolt is accounted for and a professional team following mountains of procedure and documentation.

It gets glossed over but is the entire reason they chose that team. Bruce Willis designed the drills they were bringing into space. NASA stole his patented design and altered it. Unfortunately the alterations caused numerous failures and mechanical issues. They assumed bringing in Bruce he would be able to fix their engineering issues without much fuss. He deduced the entire NASA design was faulty and irreparable. It would be easier to train his own people how to go to space and use a drill they're all familiar with than to retrain NASA astronauts on how to operate a previous generation of drill.
