Developer required for Magento 2.0 based Jewellery portal

Hello, We have a website built in Magento 2.0. It is an online jewellery retail portal and are looking to get some updates made in that since our current developer went AWOL without any contact. Tasks include: > Creating canonical URLs for all pages on the website > Implementing dynamic structured data markup for 'category pages' and 'product detail pages' > Integrate order tracking ( our shipping partner is BlueDart) > Fix a lot of CSS bugs left unfixed by previous developer ( Crossplatform - for mobile (iOS and android), tablets and desktops ) > Integrate pagination in the website for all 'category pages' which are lazy loaded (Proper usage of rel="next" and rel="prev" ) > Optimize website for pageload time (which includes moving all static resources(scripts, css and image files) to a subdomain) > Integrate Google shopping feed which is compatible with jewellery niche > Implement data layer and transaction tracking with Google Tag Manager (Development URL and access to current code will be provided over Private Message to applicants directly). We are looking for a development partner who we can work with on a long term basis. Please provide best possible prices in your quotation because this is going to be an ongoing project.
