eBay Postage Rates Tables setup in Australia

Currently we're dropshipping on eBay Australia and we're looking for someone with experience creating postage rates tables, for eBay and maybe Amazon Australia later. We have suppliers who have started charging certain amounts for postage, that need to be automatically calculated and added to the item price at point of sale.
This is possibly a short term role, but depending on experience and skills (customer service, creating listings and product research etc) it may be long term, working with other Virtual Assistants on a team.
