Finishing woocommerce

Hello, there. Web developer services are required. We need to redesign woocommerce for partner products. I will try to describe the task as much as possible. (1) limit the basket to one partner product. That is, in the basket can be a lot of ordinary goods, but if you try to put in the basket partner goods, you need to offer to clean the basket, or continue shopping without partner goods. At the moment, the partner product is working past the basket and the order is not formed. (2) we need to register with the database after the order has been placed. And you need to take an additional step: a window with the text should pop up To complete the order, go to the partner’s website, and go to the button. The button should be sewn with the affiliate link, which is indicated in the appropriate field in the product card and additionally add the order number parameter to this link. So that we can track who clicked on the link on the partner’s website, and who then accrue cashback. (3) if you take up the application, send in the application how much you estimate the work and what time it takes for you to perform the task. No high prices, I am looking for a budget option. Thank you.
