Betareaders wanted

I'm starting a new YA novel, post-apocalyptic, fairly dark but realistic dark not just dark for the fun of it, and where the female MC cross dresses for safety. The story involves a trip halfway across the continent on a scientific recovery mission, with giant monsters, bandits, raiders, and other problems plaguing them.

I want to see if I can finish it quickly without showing it to the world as I'm writing it. So I would like a few people to act as beta readers for me, and kicking me in the butt if I slow down.
I've got most of the first chapter written already, so if you're interested I can send you the bit I've written and see if you like
