Occasional Reliable Sitter For One Year Old

We are looking for a sitter to watch our daughter W. occasionally weekend evenings. She typically goes to sleep around 7 p.m.

so most of the work would be watching the monitor, comforting her back to sleep etc. We would ideally like someone who would be willing to come meet W. a handful of times prior to sitting so that she could get used to them, as to not be scared in the event she wakes up while we are gone and would be willing to pay for these meet times as well.
