"although I've been known to run and do sledgehammer swinging in twenty below wind chills."
I would DIE!

I think with the New Year getting close, you'll be able to drum-up some good interest and the early mornings will prove successful for you! If you get "why so early in the morning?"-type questions, just let them know that it's a lot easier to roll out of bed and get it done first thing vs. later in the day! Let them know you're not gonna take excuses!
Best of luck to you!
