A shipping module needs to be created for an existing install of osCommerce (CREloaded). Currently, only sample data is loaded so you can purge the database if you need to.
The client needs to be able to flag some items as "frozen", all others "dry goods" by default. The shipping cost will automatically be calculated via one of THREE lookup tables: one table for dry-goods-only, one for frozen-only, and one for mixed. The system must be able to determine on it's own which table to use, and the client will fill in the values for the tables.
This can be done by simply adding a boolean "frozen" value to the catalogue item table and some basic if/then statements at the shipping end. Existing multi-table modules can most likely be adopted from the contributions over at osCommerce.org.
We need this module ready/installed within the next 48 hrs at the most. We can pay around $75 for this project.
