Here is what I would attempt:
Today: pickup all the stuff you need for brewing (Hank Hill voice: popane, propane accessories...).
Tonight after your kids are in bed: test your burners, start your yeast and clean any equipment that needs it so that you will be ready to go first thing the next morning.
Saturday Morning: Dough-in your grains and then run off to see your lady.
Saturday Afternoon: Finish the rest of the brewing (sparge, boil, cool, pitch yeast).
