Hello! I am looking for a WordPress specialist for technical refinement of an already completed, working one-page website (landing page) created with Elementor. The site sells one product (a multifunctional folding workbench).The goal is to prepare the page for launching advertising in the European market (Poland, Germany). The task is purely local; everything must be implemented using standard, safe, and reliable plugins, without writing custom code from scratch.Clear list of tasks:Multilingualism (4 languages): Set up switching and operation of four language versions (Ukrainian, Polish, German, English) through Polylang, WPML, or a similar plugin. I will provide all texts for translations fully prepared; your part is the technical setup and careful placement of content.Multi-currency (3 currencies): Set up currency selection (UAH, PLN, EUR). Important condition: prices for each language version must be entered and fixed manually (for example, clearly 6000 UAH for Ukraine and clearly 500 PLN for Poland). Automatic conversion at a dynamic rate is not needed.Payment system (Stripe + BLIK): Integrate a standard plugin for accepting payments from European cards and the Polish BLIK system. Integration is done under a Ukrainian FOP of the 3rd group. I will register the account in the payment system myself under your guidance; your part is purely technical connection and testing of the payment.Delivery block: Add a ready text-graphic block with information about the conditions of international delivery via Nova Post to the page. No complex API integrations, cost calculators, or tracking systems are needed—this is just an informational section.Layout adjustments: Check and adapt the display of the site (desktop + mobile version) after adding language plugins, so that the layout and fonts look neat and nothing is misaligned.Requirements for the performer:Experience working with WordPress, Elementor, and localization plugins.Practical experience connecting international payment gateways (Stripe) for Ukrainian entrepreneurs.Understanding how to do the work quickly using ready-made solutions.In your responses, please indicate the fixed cost of your work for the entire turnkey project and realistic deadlines (we are looking for a specialist who can complete this task in 3-7 days). Proposals for developing custom backends from scratch will not be considered.

About the project: A selling landing page is required for an author's online intensive on the active corporate website of a law firm. Website platform: WordPress.

Improvements in UX/UI are encouraged, including the addition of neat micro-animations, shadows, and modern effects (features) that will make the page more attractive and selling while maintaining a strict corporate style.2. Integration with CMS (Editability):Critically important: The landing page must not hang on the site as "bare" HTML code. The page needs to be assembled using a visual builder (Elementor) or implemented through flexible fields (ACF).The client must have the ability to easily change any texts, links, rates, and photos directly from the WordPress admin panel without interfering with the code.3. Technical requirements and responsiveness:Full responsiveness of cross-browser layout: Desktop, Tablet, Mobile. The page must display correctly on all types of devices (including the proportions of 3 vertical video testimonials).High performance: Basic loading speed optimization (Google PageSpeed) is mandatory. Images must be compressed and converted to WebP format, scripts and styles must be minified.4. Feedback form (Lead generation):The landing page has an application form (Name, Phone). It needs to be fully functional.All applications must be instantly sent to the corporate email: [email protected] is necessary to configure sending via SMTP server or use a reliable plugin (WPForms / Contact Form 7) to ensure that applications do not end up in the "Spam" folder.5. Multilingualism:The current site implies the presence of three languages (RUS, KAZ, ENG).As part of the project, the performer must set up multilingualism for the new landing page (using the built-in site plugin).During the task execution, the client will provide ready translations of the text into Kazakh and English. The performer must create and format these additional language versions of the page.6. Integration with the main site:Set up a transition to the landing page from the main site.A new button or menu item (for example, "Online Intensive") must be added to the main menu (in the header) of the active site salyk.net, which will lead to the address /online_intensive.Additionally: create a language switch function rus/eng/kaz in the style of the site.
