Budget: 27000 UAH Deadline: 21 days
Regarding the timeline - the guideline is 2-3 weeks for a careful transfer, assuming there are not tens of thousands of products and no complex connections to consider. 5000 UAH for such a task seems risky and too low, because with an advertising budget of 300 dollars a day, mistakes in links, analytics events, or modifications could cost more than the entire migration =/
We would go through a technical migration plan - exporting products from Prom.ua, checking specifications, modifications, and translations, setting up the structure in Khoroshop, creating a table of old and new links, redirects, basic SEO checks, transferring analytics events, and testing orders. The nuance here is that the beauty of the design is secondary until it is proven that traffic, analytics, and conversions survive the move.

In general, it's fine to go in stages - first an audit of the current site and a migration plan, then the actual transfer and tests. Measure seven times - transfer once; this is not pretentiousness, but a saving of the advertising budget.
