How Do I ... Create a script/agent in MAC OSX to Mail Automatically

We have many sales people on the road that are constantly relying on e-mailed proofs (.pdf files usually) to arrive in a timely manner for presentation to their clients. Our Creative Dept. would like to simply drop the proof file in a folder on the MAC OSX server that is indicative of the recipient Sales Rep. and have the file automatically e-mailed as an attachment to that Sales Rep. In spite of a long exposure to assembly and Fortran languages, I'm not familiar with scripting in MAC OSX. Has anyone created such a script or can assist in pointing me in the right direction?
