465408 PHP small script change

We need an experienced php coder who can make a quick change to one of our scripts. We increase our insurance premiums annually by running a script but with the new year approaching we need the script to take that into account. The edit should not take longer than a few minutes and most of the time will be taken up explaining what it should do but all in all it should not take longer than an hour. We'd like to work with someone who is a very experienced php + mysql coder in order to work on future projects with us, must have no problems with English whatsoever and must be available on skype via text and audio. This project is very urgent so please dont bid if you cant start working on it immediately.
