Hi, Archy! Sounds like you've got lots of skills in the Maintenance department already!
That's a heck of a schedule! Wouldn't worry about breakfast too much - pretty much anything will work. I've run out the door a time or two with peanut butter in my mouth and the spoon sailing toward the sink - not the best, but it'll keep me going for a while.

Or a piece of pizza. Or a few slices of lunchmeat. Even better - a hardboiled egg. I'm a protein fan.
Meanwhile - welcome aboard - again!
