Chris ... just an "FYI" ... 2013 is the second year of the customary two-year scheduling cycle; most schools will reschedule on a two year cycle for 2014 and 2015 once TAPPS and UIL go through their realignment process.
You might schedule a week 5 or 6 game this year for two years and find out that in 2014 you'll need that week to fit in a new district opponent.
Plan on making a one year deal for 2013, maybe with the agreement to extend it to 2014 and 2015 subject to redistricting concerns.
