Small extension to application

I have an application where a Perl script parses an xml feed and updates a database. I need someone who is experienced in all 3 or the above to make a small change to the application for a new feed to be added. Please do not apply for this if you are not expert in Perl, PHP and MySQL in that order. Also this job needs someone who is able to turn it around quickly - This is very importatnt. I will give the necessary access to the winning bidder as soon as chosen. I have attached the perl script, the winning bidder will be required to explain to me what it is doing in simple terms so that I can be clear that the bidder understands the requirement prior to the project being awarded. Thanks for bidding!
