Is there anyway I can bet on who will start the season as Cleveland's QB?

Seriously, I need to know this. The team seems to love this guy Frye, the number one receiver really loves this guy, and he has never played behind an NFL quality offensive line. I know Brady Quinn and Kenny Anderson are in the mix, but (as of midnight, August 13th, I am willing to lay down money at a casino with a sports book that this will happen, and I have a free round trip ticket to get to said casino. How would I place such a bet?
