Start Sharepoint workflow "x" days before expiry date

Question

I want to create a workflow on a Sharepoint list and it should send a notification email.

The problem is that I want this workflow based on expiry date(send an email 30 days before the expiry date) and I am not creating or updating any new list items.

I know workflow can only be created if any item are changed/created but I have seen some buzz around on the net that this can be possible using SPD.

Any suggestions would really be appreciated.

Thanks,

This should give you a good start - it covers workflow, timer jobs and some 3rd party products that can do what you are after.
