D.G.
I've used Sitter City to find our sitters (2), and it's been wonderful. I agree with pp's, in treating the process as an employer would. Here are some things I did in finding my sitters:
1. Be VERY specific in your ad listing your childcare needs & expectations.
2. Get 3 verifiable references & check them BEFORE setting up a time to interview.
3. Interview in a public place, NOT in your home. (Safety reasons), ie.. starbucks, denny's etc.
4. DON'T list a specific pay rate & discuss at first interview.
5. Follow 1st interview w/a 2nd interview at your home with your child & significant other present.
6. Have the applicant spend an hour or two w/your child, some of that time you are present seeing how they interact & then part of it where your gone (close by). We paid our sitters for their time which was appreciated.
These things REALLY helped me in deciding a sitter & helped to weed out people that weren't a good fit. Also, like any job, if the person is truely interested, this shouldn't be a big deal. We've had two dependable people now for over 6 mos. & it's been wonderful having people to rely on other then family.
Good luck to you & congrats on the new baby!!
