Hi Alric.
Fair play, sounds like an adventure. Not sure about hiring, I suspect you might draw a blanks there, but a good place to start with partners down here would be the West Cornwall Training and Bouldering Facebook page (linked). There are a few locals living and climbing in St Ives at Clodgy etc and a bunch of folk who get out fairly regularly in Penwith generally, so you should find someone.
Good luck with the trip.
Tom
