Write a modifier for OpenCart 3 - multiple prices in the product card

You need to write a modifier for OpenCart 3 (with Frame theme)
to display multiple prices in the item card.

This should be a separate extension or modifierExtradation should not "break" the functionality of other previously installed extensions and modifiersPrice are taken from an additional table oc_product_customer_prices (product_id, customer_group_id, price)Should be displayed in the product card only for the registered userVide display:99.00 p (main price in the card of the goods)
Retail price 88.00 p
Wholesale price 66.00 p.
The price is 33.00 p.

Price types are taken in the oc_customer_group_description table (customer_group_id, description)

The main price of the item must be displayed and used at the checkout in accordance with the registered buyers group. That is, if the buyer in group 3 (large wholesale), then the main price of the goods and the design of the goods goes at the price of this group.

7. If any additional price is zero or non-existent, the "on-demand" label is displayed, example:

Retail price 88.00 p
Wholesale price 66.00 p.
High-priced on-demand

The deadline is about a week, there is no rush.

Im waiting for your offer on price and terms, I will also consider the option of purchasing a ready-made multi-price module with refinement to the desired functionality.
