Apartments are great for employees to do while they're still fresh behind a wand. Great for training too on how to clean nasty carpet. I got really good at spotting from apartments and learned quickly if you hit them with a prespray that has a solvent and oxidizer you're going to get(most of) the spots out aside from koolaid or similar.
Run a resi job or two by yourself in the morning and then come help pick up the slack in the afternoon with the employee. Or hammer it hard for a few days running two trucks and leave the end of the week to do residential while the employee finishes up the remainder for the week. They won't be as good or quick as you until after a good round of them but it's a nice quick learning curve to be efficient yet do a good job.
I have a local guy coming that I traded a bit off their website design to come clean my carpet now that my year old pup is potty trained. He is going to be bring his new guy and between my son, girlfriend's nephews, and the dog it should be a good learning experience for the new guy and him.
