Through which CMS to create a catalog site with a basket?

Question

CMS

Good afternoon, It is
required to create a catalog site with the possibility of ordering goods.
Theme of the site mototechnics.
There will be 2 types of goods: appliances and accessories.
In the technique there will be: a photo (several), price (with a checkmark, when you click a fixed amount is added to the price, and the total amount is displayed), “buy”, description, characteristics, advantages (in the same form of innovation), a module for collecting your equipment (a number of accessories is added to the equipment through a tick with the withdrawal of the total amount), recommended products for each equipment.
Accessories: photo, price, "buy", description.
The rest of the pages are blocks of text with photos, tables,
Home: header, carousel, catalog, "bestsellers", recently added.
Cart: no need to connect ecomers modules, sales through the site are carried out through the feedback form, we find out the balance, send an invoice for payment to the client, he picks it up in the store with offline payment, or we take it to the mall. But in the future we plan to integrate with the 1C database, respectively, the balances will be visible on the site, and then we will already introduce online payment.
Basement: contacts, map.
Necessarily, the maximum opportunities for SEO settings.
Again, I explain this, the site is more of a catalog than a store - you don’t need any store "tinsel", the client sees the equipment, description and where it can be viewed live, at the same time grasps with a glance what can be taken for a kit, etc.
There is a site now, but it is on the tilde constructor, the possibilities there are limited, and we plan to expand it. I would like the site to rank better in search engines, because I think that due to the too loaded tilde code, it is difficult for search engines to work with it, this time. Two, we are the second store in our city, and we cannot break into the first positions in search engines, the first store works longer and it is difficult to get ahead of it. (there is contextual advertising, social networks, meta tags and H1 are filled on the site, there are not only a large number of external links).
There may also be difficulties with the design, since the current one, in principle, suits, but again, the site was assembled by non-specialists, and the logic of the pages could not be properly designed.
We will fill the site with goods ourselves, we only need the basic pages and blocks that were described above.
Here's the question, opencart? How much can such work come out in terms of money (the design will need to be pulled on the old one) and is it worth doing on this engine? Do I understand correctly that only hosting and a domain will be included in the costs?
Bitrix? Maybe he also has templates for reasonable money, you can work with the template to customize everything for yourself? In this case, how is everything in terms of money? Is the license paid annually? What injections at the start?
Maybe there are some other solutions?

Answer 1

Through any. It is possible even without CMS at all.

Answer 2

The issue of creating a site with online payment should be considered as follows:
The choice between a free open source platform and a commercial
-I do not advise, often these templates are made especially difficult for third-party developers to support
- you can, but the question arises why buy a template to remake it? It is better to immediately order a template for yourself.
- popular templates from 20k rubles + will remake the same amount
- For example, a Small Business license is 35,900 rubles once and 22% of this license is annually purchased for renewal to receive updates. there is support for CCP, marking
- an individual online store starts from 100k rubles
3) Can there be any other solutions?
Of course, there are few free ones if you look at ecommerce systems, and among them there are none adapted to Russian legislation, but you need to look at ecommerce systems.
From paid ecommerce, for example, there is a cs-cart license there for 25,000 rubles.
