Sending server-side file as an attachment

[matterhorn]

Hello all,
I am trying to send a pdf that resides on the server as an attachment. Potential customers provde their information through a coldfusion form and I am trying to send them the PDF once completed. Any idea on how to accomplish this? I am aware of the cfmailparam tag...but it seems like that is only for files on the client side. Any help would be awesome...I have beaten my head against the desk for quite a while on this one.

Thanks,
Matt
