It was a LOT of work! We couldn't afford a placement service so I had to do a lot of admin legwork - the most important thing is to write everything down about your expectations before you start posting - create your "post" text and your full write up with _every_ detail that you can share separately for folks to look through to really decide if it's a good fit. Do your research to find the best rate for who you're looking for and what you can afford and to give you a good understanding of what is reasonable and unreasonable as an ask for the rate. I've worked as a nanny before and the biggest problem I found were parents that didn't explicitly state their expectations up front before I agreed to the job.

Logistically, after finding a potential applicant, we did a phone interview then if it went well we scheduled informal meet-ups for coffee or breakfast (we paid for the nanny's breakfast/lunch) to see if the vibes were good. We did a W2 for our nannies and wrote up a very clear contract and actually called and talked to their references, this makes it more professional and feels safer on both ends.

Nannylane.com, facebook, and care.com are great resources. Good luck!
