Thanks everyone. I found a basic sauce recipe called #5 that I'm going to try and tweak to make it my own.
1 cup ketchup
1/2 cup cider vinegar
1/3 cup brown sugar
1 tablespoon worchestershire sauce
1 tablespoon rub
Seems pretty simple, basic, and it appears that I can add more ingredients to make it my own distinct flavor (hopefully similar to Head Country)
