develop woocommerce plugin - Cost of product price

HI i want to build plugin about cost of product. Each distributor has different terms than what appears from a list price step 1 - There will be a field in the database that will pull the dollar rate and store it there (no need online, these will pull data once a day) step 2 - in woocommerce>product I can add a distributor and give the distributor's name and conditions from the list price (Whether the price list is in NIS or USD (If the price in the price list is in the dollar it seems to me that we will need another external field that will determine what the dollar rate is, because sometimes the dollar is a fixed price, sometimes a dollar rate with a certain addition, etc.) , a discount percentage if there is, etc.) have example below step 3- on the product page I will have a select button where I can choose a distributor (from step 2), in another field to list the price that appears in the price list and in another field will be the calculation of the result (image 2) step 4 - The cost of a product should also appear in product> all product in wocommerce page (Image 3) for example: 1. Distributor 1 - Dollar exchange rate + 0.05 plus 10% discount Dollar Rate - 1 Dollar = 3.692 NIS (New Shekel) - Round Up 3.7 The price of the product appearing in the price list is - 100$ My price will be 3.7 + 0.05 = 3.75 3.75 (dollar rate + 0.05)*100(price of product in price list)*0.9(10% discunt) = 337.5 to round up 338 NIS you can take the doolar rate from here - [login to view URL] 2. Distributor 2 - The list price is in NIS, so no conversion is required 20% off the price of the price list in NIS without conversion. example: The price of the product appearing in the price list = 300 NIS I have 20% discount the product cost me = 300*0.8=240 NIS 3. Distributor 3 - List price is in dollars The dollar price determined by the distributor is fixed and is 4 NIS example: i have 15% discunt in this vendor The price of the product appearing in the price list = 200$ results = 200*4*0.85=680 NIS IMPORTENT!!!
