Optimize Magento 2 site both design and coding -- 2

Hello, We are in search for a developer who can optimize our current webshop in Magento 2. We have a more detailed brief, but overall the jobs is regarding: Hello 
 Here comes the project brief. Please ready it through and get back to me. 
 Shop:[login to view URL] The theme is Molly Magento 2 General fix: Responsiveness - has to work and look good on all mobile devices - E-mail templates - they have to be the same all of them and text has to align with margin and look nice - (Order details are not looking nicely) - Order number needs to start from “45739” In the danish language it shows english text. We have used the inline translation but it isn’t saved. Maybe the setup is wrong. [login to view URL] Also [login to view URL] "Go back" should be a button. Language set up with nice dropdown, (Ill show you examples - Button in top left corner and in the footer, with drop down, so people can choose their country. The countries should be divided into Europe, Asia and so on with the continents - Create an url/store-window called “/en-int” for the international languages fx. - Store window: Philipines could be “/en-int” since they speak english - Same languages as all the Bering watches have Optimization: Make the whole site load faster (it’s really slow) Design: Make the design more rich and of higher quality. There are much white in the background, our brand must look luxurious like Daniel Wellington and Bering, but in our own style. Usability must be better, so please make the buying process easier. At the moment purchasing as a “guest" is very confusing. Payment: - “My account” needs to get a retouch so it looks more simple and nice - Set up Stripe so it works smoothly - at the moment it is very confusing. At the moment you have to add your credit card and then go back and press buy - not a good workflow. Maybe Magento core Stripe is better? Product page: - “Email to a friend” does not work properly: [login to view URL] - Please see attach images, placement is not good. Setup up on product page: Instagram feed must be set up so when we make a hashtag like: “montaravally”, then the image show on the Montara Vally watches page from instagram. Ill show you examples Theme corrections: - Please change the theme name to “montarawatches” in the source code. Google Console bug fix. Looking forward to hear from you. Regards Jesper
