osCommerce Customized B2B Module

osCommerce Customized B2B Module: Job Requirements: This project is to create a customized B2B module for osCommerce shopping cart I need a module that allow me to create multiple customers groups and enable me to give more than one discount to each group depending on the item, the category, or the manufacturer they are buying. The way I imagine this module is explained in the following points.: I want this module to contain the following tabs or menus 1- Discount Map:: Here I should be able to choose from a drop down menu whether the discount or the mark up will be By Product, By Category, By Manufacturer, or Entire Store. 2- Method: Here there should be a drop down menu to choose between Discount or Mark up to determine whether I will be using a discount or Markup. 3- Value: Here I should be able to choose whether the discount or the markup will be in the $ amount or in the % amount. 4-Amount: Here I should be able to enter the discount or markup amount 5- Expire: Here I should be able to enter the expiration date of each Discount/Markup. 6- Add Discount: Add discount button to add more rows and discount if needed. This way I would be able to give any customer group more than one discount rate on more than one category or item as in the following example: Group A could get the following discount: 35% on Category 1 30% on Category 2 25% on item # 105 20% on item # 450 15% on the rest of the categories and items I tried to illustrate the New Discount Tool in the following table to make it easier for you to understand my requirements: [login to view URL] • When the group customer is logged in he should see the Retail price (or the original price) crossed out and the special price beside it. • Only logged in customer can see these specials (you cannot send the URL of the discounted item to any non group customer) • If the group customer is not logged in and added an item to his cart the item does not take the group discount if the customer logs in afterwards. • I want this as a drag and drop simple addition to my osCommerce Cart. No sophisticated installation because I want to install it myself. • I want this module tested on OSC v2.2RC2a because I will tested myself on this version. • I don't want this addition to mess up my template. Thank you for taking the time to read and thank you for bidding.
