Nannies are fine, unless you actually talk to a professional nanny. And then you'll see how they have hurt the nanny business (with the exception of foreign students, but that's another story).
If you don't know any nannies, it's okay, because you can wait for your friend the carpenter, the carpet installer, the dry wall guy, the mechanic, or the cement guy to get displaced. Basically, I'm talking about all of the trades, with the exception of plumbers and electricians (but maybe even those, too).
Anyway, it's already started. A guy I know needed a new floor. He hired three guys, bought the flooring at Home Depot. Cost of labor? $250 for two days for all three guys.
All three guys were hard working and good with their hands, while one of them was actually a skilled carpenter.
Where is this? You can't hire a skilled (likely illegal) solo carpenter for less than $100 per day in my experience. And even then, he won't have many tools or skills. I live in Dallas, by the way.
