We are based in Australia and need a way to charge our customers freight based on their postcode within Australia. We have courier zone file .csv format which has each post code in Australia is matched with a couriers carrier zone code . There is a second spreadsheet with reflects the carrier zone and a charge for freight to that location (initial flag fall plus a kilo rate).
A few zone are classified as local zone and have a single flat rate postage however when a parcel gets to a weight of 25kg it needs to trigger another flagfall rate for additonal freight.
I am looking for a solution where that information can be used at checkout so our customers can see real time what their freight charges to their location will be.
I am looking for somebody who has experience with volusion.
If the project amount is not correct for this kind of work can somebody please let me know
