Budget: 27000 UAH Deadline: 14 days
We can take OpenCart 2.3 - not only to update the appearance but also to bring the mobile logic of the catalog, forms, cart, and applications to a normal state. On Windo.com.ua, I see a catalog of doors and windows, a calculator, measurement and consultation forms, a client center - here it is important not just to repaint the pages but not to break the applications and product logic.
The estimate for the basic stage is 35,000 UAH, 14 days. It includes an audit of the current theme, prototypes of key pages, adaptation for mobile, refinement of OpenCart 2.3 templates, checking forms and the cart, basic speed, and testing.
Access to the admin panel, files, a test copy of the site, and a list of modules that cannot be touched are needed. Please clarify what more functional means for you - new blocks, changes to the cart, calculator, filters, applications, or personal account?

In general, we can keep it simple - first, we establish technical and visual order on key scenarios, then we add functions without chaos =)--
