We are looking to redesign our [login to view URL] The site is made using WordPress. Here are the things that we need to do: 1. Redesign the site 2. Add multilingual support (English, German, Italian). The current language is Croatian, and it should stay as the base content language. We have language experts we need just that the feature is integrated. (the plugin should do automatic translation and then the language expert should additionally edit the text to comply with the grammar and other standards. ) Based on customer location the system should land the page on the customer language base on setup. 3. We use WooCommerce as an e-commerce plugin. Based on customer location the system (geolocation) the system should offer the customer pricelist with the prices for the region. Example: the customer is from Austria (geolocation), the language of the pages is German, and the prices are as set for the Austrian market. 4. We have a plugin provided by our logistical partner that needs to be included in the new version of the Web site 5. We have a link (plugin configured correctly) between the Facebook/Instagram accounts that works fine and needs to be preserved 6. We have google AdWords configured correctly and needs to be kept as is. This item needs to be offered as a separate item! 7. We need a plugin that could search all sales based on the timeframe: month, week, or day and based on the query it needs to create a downloadable CSV file. All rights for that plugin should be in our name, and we should be able to distribute it as a paid or free plugin depending on our decision. The developer in this case will transfer all the rights to us, and will not have any request further. If we are intending to hire the same developer or somebody else to maintain the plugin that must be our responsibility and our right, and the developer needs to agree with such in writing.
