- upgrade to magento 2 - webkul marketplace plugin is used. - Keep all current functionalities. You can use different or updated plugins like page builder, social login, one page checkout etc. But similar functionalities will be required. - Update layout of all pages based on a new responsive and attractive design - Fluency in CSS, php, js, AJAX, is a must becuase there may be design conflicts from previous build. - Existing website is custom coded. So only installing a new theme is not a solution. - All minute aspects of the website has to be considered, like cart behaviour, error pages, link hover color, font, alignment, mobile responsive for each element etc. - CCAvenue iframe integration - Do not bid just to acquire the project, I do not wish to waste your or my time. Only bid if you can achieve the goals in a professional manner in a limited time period. - ONLY ONE MILESTONE. TO BE RELEASED ON COMPLETION. - Incomplete or buggy project will not get any payments - Developers must test everything from their side without waiting for feedback - There are some custom pages and layouts on the website as well. They must be imported to new design as well.
