Bigcommerce and Australia Post eParcel Integration -- 2

Hello, I noticed that you already worked on a project for the above request. I'm after the same thing. I'm assuming what I need is something to convert the exported Bigcommerce file (xml or csv file) into something that eParcel can use. Can you please let me know what you need from me to complete the task? I was wondering if you'd be happy with US$100 as there's quite a few freelancers on Google who have also completed this task?
