Development of an online store

Hello, I need to make up this layout
PC: https://www.figma.com/proto/RbOe4Z62GhFywMKSypDyQ6/Kharkivmebel?page-id=0%3A1&node-id=3%3A2&viewport=291%2C48%2C0.36&scaling=scale-down-width

Requirements:
1. CSS preprocessor - SCSS
2. Grid CSS FlexBoxGrid.
3. Do not use JS in layouts, only layout of the provided layout.
4. Using the BEM layout methodology.
5. Use Mixins
6. Use sass-mq / mq libraries for adaptive

Examples of the style of class naming:
hm- is a prefix that will be used in all BEM-related CSS classes.
hm-table - Block
hm-table__tr - element
hm-table__tr - is-color-green or hm-table__tr - isСolorGreen. Just choose one naming method and apply it throughout the site.

I would like to know the price and terms. thanks
