ZEN CART MUltiple Qty Boxes

I am looking for a zencart expert who can add multiple QTY boxes to my shopping cart so that products with attributes have their own individual qty boxes. AT present each product only has one qty box, however we have various options for each product and need it so that customers can select multiple items. I currently have a mod installed which displays attributes on the product listing page and so this would also need to display multiple qty boxes. You must have proven experience in ZENCART, the budget for this project is $60, no more, if your bid id higher than this it will be removed.
