New postcode module for Zen Cart for adnan/zeeshan

Part 3 - shipping 3. I need to create a new shipping method that will be applied to all orders. It should be free shipping to most of Australia, except for a list of postcodes that I will provide. Anyone in this list of postcodes needs to have an extra postage cost on their order. Also, on the product description, when you click a link a lightbox should appear that lets you type in your postcode, and be told if you will have free postage or not. [login to view URL] is a list of shipping costs per postcode. The details: $30 shipping cost for all postcodes with: 08** 4371-4377 4381-4390 4406-4422 4425-4426 4467-4471 4474-4482 4486-4498 4518-4521 4552-4554 4571 4574 4694-4695 4715 4717-4718 4720 4736-4739 4743-4746 4751 4799-4800 4807 4819 4823-4830 4871 4874-4876 4890 $29: 6431 6434 6437-6438 6440 6443 6447-6448 6450 6452 6535 6642 6646 6770-6799 $20: 6320-6324 6326-6328 6330-6333 6335-6638 6341-6349 6353-6359 6397-6398 6420-6430 6432-6433 6436 6442 6445-6446 6484 6528-6534 6536-6537 6612-6640 $15: 6043-6044 6240 6243-6270 6275 6280 6290 6312 6319 6321-6322 6350-6352 6361-6389 6392-6396 6407-6419 6460-6484 6487-6490 6507-6527 6568-6575 6603-6609 6613-6620 All other postcodes are free.
