I personally do not PAY to advertize anywhere .... IMO there are way too many FREE options out there that WORK to consider paying for advertizing!

When I started out I had my ad on over 20 free sites where it is just 'there' you do not have to up date it or anything ~ however I ask all my non-referred contacts how they 'heard' of me most of my inquiries come from either HERE, Godaycare or Kijiji or they googled and found my website so those are the venues I tend to spend more time 'advertizing on'.
