Damon,
I know it sounds cliché and I certainly don't want to insult you. However, it's all in your perspective.. Some guys, including myself would love to experience the problems you're having as opposed to not having the money to buy new or upgraded equipment to expand into new markets or worse, being forced to close up shop.
These are good problems to have! Is it fun.. nope. But these problems are a testament to the simple fact that you are doing everything right and succeeding. You're winning even though it feels like you're losing.. Is it perfect and exactly the way you'd prefer to experience a growth spurt? I think we all know what the answer is.
Use this opportunity for growth as a positive as much as possible. Retrain this carpet cleaner so he does everything exactly as you would.
As Willy said, train him right, treat him right. You need help and he needs work because he's got bills that need to be paid.. this is a mutually beneficial situation... You wouldn't be in this spot if you didn't know what to do. Follow your gut.. you'll be fine.. You got this!
Remember, this is a good situation to be in. The hardest part is just seeing it for what it really is, instead of focusing on what it isn't.
I wish you much continued success with your business.
