HI We have an ecommerce software developed inhouse a few years ago that needs upgrading by adding ajax/jquery filters similar to magento software. We will provide the database tables which will hold all the information you require to be able to develop what we require. We require your programming skills only. A couple of examples of sites we We require functionality similar to: [login to view URL] [login to view URL] Please notice how the results changes when a filter is checked in the left column and when the show number of products per page (dropdown) is changed. The way the filters are displayed in the left column can be one of text, colour boxes (like atlantic site), images or sliders (for price). If the filters are images, our ecommerce backend will allow an image upload for the choice. We do require this project to be completed in the shortest time possible so please only bid if you are sure you understand our requiement and have the experience to complete the project and. There is no budget range set for this project, you are free to place your bids as you wish.
