Customization of Zcart multivendor script

Job ID: 34832441

Budget: $30 – $250 USD

I need to customized this script as it is https://www.zcart.incevio.cloud/ with as below:

- add auction option when adding a product
-add a new offer when adding the product (with selective options, automatically accept the offer if it is better than_____ and reject the offer if it is lower than______)
- add the seller to set the estimate of the delivery time of the package from the carrier after receiving the buyer's selection for the desired transport when the seller processes orders. After the end of the submitted evaluation time, the buyer has 3 days to confirm the item received and can claim or open the dispute and at the end of 3 days they will have the opportunity to leave an evaluation for the seller, such as responsible, speed, response , quality. if it can't, automatically 5 stars will be posted by the system for each category.
-add buyer gets -3% discount if you pay by Bank Transfer, Cash App, Zelle, Crypto
-Add seller verification with KYC.
- add a button link to another domain for all articles with a description of 20-100 char, to the right of the article price by flashing or circling something in the shape of a sunflower
-add a secure payment badge detailing that the seller will receive funds once Bayer confirms and the review has been posted to the seller's account.
- add addition of payment by credit card using Square Up because with this processor I have a discount for each transaction better Than PayPal etc and I want that when the auto tracking detected delivery tracking number and Buyers confirmed after 3 days or auto confirmed by system if Bayer didn’t confirm it, in this moment automatically the seller passes the payment and the commission that we set in the admin panel is kept.
-the same add on we need to the app.
