Need an Wordpress Ecommerce (or php) Expert to make a tweak to a file

Hi

I am looking for someone ASAP who is knowledgeable in PHP and/or Wordpress Ecommerce.

I have an installation of Wordpress 3.5.1 and Wordpress Ecommerce 3.8.9.5.

Basically there is a file which sends a notification email and I need to add a tweak to the email so that it shows the CATEGORY of an item in the email.

The file is located in wpsc-includes/purchase-log-notification.class.

I believe between lines 101-105 is where it currently displays a table of details such as the item name, price, quantity and total.

This is where I need the category to be included.

Looking to get this done and paid for as soon as possible please.
