Budget: 180000 UAH Deadline: 45 days
In terms of deadlines and budget - the guideline is from 45 working days and from 180,000 UAH for a full first version. If we are not just creating a beautiful website, but a proper sales system with a catalog, payments, delivery, a personal account, and product management - it usually turns out cheaper only on paper =)
At the start, I would suggest going through a short design phase - 3-5 days. In it, we clarify the structure of the catalog, filters, order scenarios, payments, delivery services, roles in the admin panel, product import, and age restrictions (18+). After that, we can provide an accurate estimate and not guess on coffee grounds, although coffee grounds for IT specialists seem to be called preliminary assessment.
> What is important to consider
> catalog, filters, search, product cards
> cart, order processing, payment, delivery
> personal account, order history, notifications
> CMS for products, categories, pages, and basic SEO
> speed, security, backups, and further scaling
A couple of clarifications
> how many products will there be at the start and is import from Excel, XML, or another system needed
> which payment systems and delivery services are planned
> is a separate age gateway needed and what are the moderation features for content

Overall, this is a normal project for architectural development, not for assembling on the fly. It's better to lay a solid foundation once than to heroically fix each new function later.
