Other than word of mouth most of my clients in the last couple of years have come from kijiji, daycarebear, godaycare in that order. Stay away from craig's list as that is prone to more weird inquiries than other sites for some reason. On kijiji I know how I look at the ads when I am just browsing and that is by typing in the subject I want so in my opinion not worth paying to be on the top or for special services since a lot of those ads are ignored anyways and will still come up in a search a person does.

There are other places you can list. On the www.ccprn.com website look under for caregivers and there is a document listing places people have said they have placed ads. Some are free and some are not and some seemed no longer active the last time I used the list but still it is a resource of options.

Having a website does help but it takes awhile usually to build up traffic to it. Make sure you list your website in the descriptions.
