This isn’t a typical UI/UX design, it’s more like a quick mockup of possible improvements and adjustments to your existing web pages. We’d take a look at your current web page, compile a list of possible improvements, and a quick mockup.
What we offer for a single small task is a mockup of one of the web page templates, for example, the mockup of the product page is covered under 1 small task. Please, note that all the HTML and CSS work needs to be handled in separate, development tasks, and the number of tasks highly depends on the number of changes and will be assessed by the development team.
