Calculator for the Print-On-Demand service website

Dear ladies and gentlemen, designers🙂

Thank you very much for responding to this project.
I have reviewed all your works and realized that my responses will be quite similar and that there was not enough specificity in the competition conditions. Therefore, I need to provide some clarifications and explanations.

Layout
The idea of spreading the calculator interface across three screens (stages) is quite suitable for mobile devices and possibly tablets, but for desktops, we would like to retain the ability to display the calculator on one screen. For example, choosing the display option of the calculator in the backend.
Perhaps this question is more for developers than for designers.

Order of blocks
First, the client chooses the file format from which the book will be printed.
The file format determines the size of the book and how many pages it will have.
Then the client chooses the binding (hard/soft).
And the color of the block of pages (color, black and white).

So the optimal order of blocks in the book parameters is as follows:


Minimalist design
That is, we refuse infographics that lack functionality.

Color scheme
We settled on:
light green - main color;
additional - at your discretion;

Stylistics
Less text, overly long dropdown lists, etc.

More icons, graphic solutions, animations, etc.

Example:

This menu will produce a list of 12! items when used, as the printing house can make books up to 1200 pages in increments of 100 pages. Such a solution will not be convenient on mobile devices and does not look attractive at all.

Among your solutions are the following:

This is better, but has certain drawbacks:
- takes up screen space, which is critical for mobile devices

- if the allowable number of pages increases, the interface will need to be redesigned

There is this solution (implemented on the site fozzyshop.ua):

It requires less screen space

Any number entered in the backend is automatically distributed across the slider

Such original and interesting solutions would be nice to see.
Perhaps there are some ideas regarding the animation of icons - rotation, transformation, highlighting, shadows, etc.

There was also no explanation regarding additional services:
File search
File cost

Already now, the number of additional services has increased, so this option also needs to be scalable.
That is, we have an icon "Additional services", clicking on it opens a pop-up with a list of additional services.
It is better to make the list in the form of icons with a tooltip than in the form of a text description.

Dear, I apologize for not notifying you earlier, but I would like to point out that, although the interface language in Figma is Russian,
the language of the competition interface is Ukrainian

Rating system:
5 stars - winner
4 stars - candidates for winner
custom design (icons, fonts, animations), all wishes from the contest description taken into account
3 stars - decent (2-3 flaws) recompositions of the basic (our) design or custom
2 stars - attempts to recompose the basic design or even custom with more than 3 flaws

Dear, in the process of working on the calculator, we found an interesting idea for the interface layout, so only work based on this mockup will be considered further.

Please use this color for the main theme tone,
