How to set custom price in opencart products?

Question

I downloaded the latest version of opencart (3.0.2.0). The pricing of my product depends on various parameters, namely: size, color, quantity .

By quantity, is there any default function to set the price range, for example, for 1-500 pieces of one price, from 501-1000 discounted prices? My products are bracelets, so I calculate the price based on the text they want to print, range size, quantity range . By default, opencart has a function for options, but my options have auxiliary parameters (dependent parameters).

I read other answers in the community for dependent options , but could not find a working solution and the same one for conveying a custom price. How can I edit core files so that custom prices work?

Product data is stored in a database as well as price. But as users customize the product, I want to change the price. The change in price should be reflected in the shopping basket and should remain the same at the checkout. How to create helper options in opencart? Creating additional options with prices will also solve my problem with the price.
