Help with a simple email script for OSX

I would be so happy if someone could assist me in creating an Applescript to send some emails. I have seen a few examples but I am not confident that I can adapt them to my own needs.

I need to send the same email (subject & body), one at a time, to a list of addresses on a .csv file. The only point is that the email has to send from a specific Mail account within the Apple Mail program. I am using Apple Mail 5.3 and OSX 10.7.5

Many thanks in advance to anyone willing to help out.
