Build an Online Store

We have 2 new webshops in Magento 2.0 which need to be maintained and some work needs to be done like below example. Please only MAGANTO 2.0 experts!! Example of work to be done: - Install 3rd Party modules and make sure they are working correctly - Sales email and Invoice templates need to be made/configured according our layout. We need to have them in 3 languages. We will provide translations as soon as the English ones are made. We need all templates like Order, Order Confirmation Shipment Invoice Credit Note etc…. - On the Order, Order Confirmation and Invoice need to have a ‘text box’ where customers can put their "Order Reference Number", need to be possible to insert text in "Order Reference Number” from Front as well as Back End where making an Order. Probably this Module will do the job so it needs to be installed and configured: [login to view URL] - Site needs to be set up for 3 languages in the same template. Probably it means that Homepage, Block, Pages, etc… need to be duplicated in order to be able to have 3 different languages, right? Please ONLY MAGENTO 2.0 EXPERTS which are willing to work on hourly fee and can give fast support!! Gerhard
