How do I find a special pet sitter?

Here’s the specifics. My husband and I travel a lot. Molly usually goes to the kennel, but as she has gotten older it seems to be getting harder and harder on her. I pay $45.00 a day for luxury boarding but she still comes home a nervous wreck.
We have a few requirements.
1. My hubby doesn’t want anyone at our house. he’s really picky about his privacy.
2. Molly is an inside dog
3. Molly thinks she is the only dog in the world. She does not do well with other dogs. She likes to pick them up by the back of the neck and shake them like a doggy toy.
She is a Queensland sheltie mix, very smart, but quite the spoiled princess and so finding the right match is tough.
How do I go about finding someone I can trust with my baby, who could keep molly in their home, who doesn’t have other pets, and who could use an extra $45.00 per day occasionally? I’m a little hesitant about Craigslist because I don’t know who I’m talking to. Then again I don’t know any of you, but I feel like you’re all trusted friends already.
