confidentiality agreements

I would like to obtain a basic confidentiality agreement  that I can 
request  web contractors we use  to develop "back-end" website work, 
database work primarily.

I am looking for a basic agreement that ensures our firm that the 
contractors we use use will not contact our clients, or disclose any 
information they has access regarding our clients files.

Can someone point me to a place on the web that may have sample agreements 
of this type for us to review.

Thank

Monique
