Need a custom module in magento 2 - max time 2-3 days

Background of requirement : There are 10 vendors pincode based and 4 main vendors zone wise, linked with my client. The client wants to route the order based on the nearest pincode vendor. The vendor can accept or deny the order received. Once the vendor denies the order, the order then goes to the main vendor of that zone. Below are the major requirements on frontend : The user enters pincode, it is checked from backend and deliverable vendors are listed along with their price list. Once user selects a vendor and places an order the order is routed to that vendor. Only serious bidders please.
