We are looking for a programmer who already realized in Virtue Mart the following solution:
The default is an article which is available in different price scales. For this article, there are mandatory maintenance offers of 12, 24 and 36 months. In the front end the customer should select an article per click on the desired price scale (or enter the desired amount of items in case there are no scales available). After choosing the desired article in the desired price range the customer – in a second step –has to choose the corresponding maintenance which is mandatory. Only after the item is placed in the cart the customer can finish his order. As far as possible the two steps of the selection should be shown on one single page.
