We hired a nanny (person we knew from religious organization) who was young (21) and inexperienced (no long-term childcare before) but wanting to get into that line of work. It was a learning experience for both parties, and she was really inexpensive in the beginning.
There were a lot of great things with it, and a few drawbacks. Because we did not hire through a service, there was no overhead cost, and we ran it as a business with some tax advantages built in. DW and I both taught high school nearby. Some days, DW could bike home for lunch and nurse when the kids were little. Sometimes, the nanny drove our vehicle with child up to the school, and DW was able to nurse there. Lots of flexibility. She also did some light housecleaning like keeping the kitchen clean, vacuuming, and laundering kids clothes.
She was off in the summers, which she liked, and was able to take on other jobs for supplemental income. From what I know through my school, there are a few young college grads (former students of ours) that are willing to nanny until they find more secure, long-lasting employment. YMMV, of course, but there are lots of good options associated with nannies.
FWIW, I am now a SAHD. Our former nanny still nannies for other families, but is a bit more choosy, and can name a much better price. From it, she also got a lot of housesitting gigs, dogsitting gigs, and even a night-nannying gig (she doesn't care much for that one).
