Joomla - VirtueMart Discount Complement / Module

What I need is a “Buy more, pay less” Component and module for Joomla that works with my VirtueMart , this is a % discount for buying quantity of products in my store. This is if, for example, if you buy 2 items you get a 20% discount, if you buy 3 items you get a 30% discount and so on. For this I will give you access to a fresh copy of Joomla with VirtueMart and FTP account for it so you can do as many test as you need, but then, when you have it ready you will have to send me two zip files (One for Component and one for Module) so I can install it from Joomla Installation Option in any Joomla Component: The Component have to let me create as many discounts as I need, and when creating them it has to let me choose in which categories of VirtueMart products it will be apply. When creating the discount the forms to configurate will be this: Categories: Here I will choose the categories in where the discounts will be apply. Item Quantity Discount Start: This is the number of items that the client has to have in his shopping cart to start having the discount. Item Quantity Discount Stops: This is the number of items that if the client has in his cart stops the discount (normally because another one stars). I have to be able to leave this form in blank so if there is no limit for the items that stops that discount. Discount: The here I will put the discount to make, this can be in % or in $ An example of the use could be: If I create 3 modules each with this configuration: Discount 1: Categories: T-shirts Item Quantity Discount Start: 2 Item Quantity Discount Stops: 3 Discount: 20% Discount 2: Categories: T-shirts Item Quantity Discount Start: 3 Item Quantity Discount Stops: 4 Discount: 30% Discount 3: Categories: T-shirts Item Quantity Discount Start: 4 Item Quantity Discount Stops: Discount: 40% If I create those discount the client will get: A 20% discount if he adds to his cart 2 items of t-shirts category, a 30% discount if he he adds to his cart 3 items of t-shirts category and a 40% discount if he he adds to his cart 4 or more items of t-shirts category. In the checkout and in the cart when discount is at the end of the list of products have to appear the Discount and the money discounted. In some way this Component is very similar to AdvanceCuponSystem so it will be a smart thing to us it as a base to start coding (you can download it free from [login to view URL] ) and important thing is that my joomla page will use the script that you are going to code and AdvanceCuponSystem so both have to work without problem in the same Joomla. The Module: This module what have to do is to let me put in a position of my store a Banner to let clients know that if they add one product (or more) they will have a discount. It´s a very easy module and to do it easier, the module will work completely independently from the component. The module what has to do is show an HTML CODE when there is a certain number of products in client shopping cart. I will have to be able to create as many modules of this as I need without any compatibility problem. For this the module configuration will have this forms: Position: Position: Discount Categories: (The module will only have to be shown if there are the quantities of items of the categories selected here) Item Quantity Start showing: Item Quantity Stop showing: HTML CODE: An example of the use could be:. If I create 3 modules each with this configuration Module 1: Position: Discount Categories: T-shirts Item Quantity Start showing: 1 Item Quantity Stop showing: 2 HTML CODE: Module 2: Position: Discount Categories: T-shirts Position: Discount Item Quantity Start showing: 2 Item Quantity Stop showing: 3 HTML CODE: Module 3: Position: Discount Categories: T-shirts Item Quantity Start showing: 3 Item Quantity Stop showing: 4 HTML CODE: If I create those modules the client will see: If he has 1 product in his cart will see Module 1 If he has 2 products in his cart will see Module 2 If he has 3 products in his cart will see Module 3 Price, the lowest the better. I can pay max. $50 dollars but if you can do it for less the work is yours!
