For our ecommerce digital printing we need to change the attributes of Virtuemart. We must first add a specific SKU for each attribute, which must be combined with the overall product. This consists of one SKU of product and attributes must be present at the checkout, email, etc.. We also need to add the attribute for which the price should not be multiplied by the quantity of product required. Also in the detail page will appear a button to calculate total before inclusion in the cart.
Please kindly send us an offer for such an extension (for Joomla 1.5 and Virtuemart 1.1.4) with exact description of the necessary timeframe and cost.
