create oscommerce order export fuction for trueship

i have a version of oscommerce cre loaded and i need to add a feature to export pending orders to a csv file. this is a function i would be using daily to export my orders to an application called trueship that will print labels for my orders. i would need to be able to export and download the file to my desktop for processing. that's it. i hope to find someone to create this for within the week.
