I need a custom shopping cart that integrates into joomla. It needs to work on Joomla 1.0 and 1.5. I already have the joomla website complete and ready to go. I just need the shopping cart. The shopping cart needs to have the following
1. Add/edit/delete products
2. Add/edit/delete categories
3. Product prices, product image and product description.
4. Accept payment via paypal.
5. Product quantities
6. Sales tax
7. Order/Sales history.
The shopping cart must have a detailed administrative area. You are free to modify existing shopping cart scripts if you like it just needs to integrate with joomla.
I also need detailed instructions along with screen shots on how to do administrative task from the admin.
You must be very good with joomla to bid on this project. Please only bid if you are an expert with joomla.
I don't want to use Virtuemart or any existing script. I want this to be custom.
