Hi Steve,
As far as I'm aware, it's all right handed tutors. Being left handed I find is a bit of an advantage as it's kinda like looking in a mirror when watching a r/h tutor/guitarist (same when watching youtube or any other sites) - think it might take a bit longer (for me) learning from a l/h one. That's my take on it, obviously, everybody's different so you might not see it the same as me.
Enjoy the journey.
Cheers,
Gordon
