My project

I need a portal where the home page is the showcase site where he explains who we are and what we do. Then there will be the registration area where customers register, customers must enter their data and be approved by sending an OTP code. Customers on their page can see the companies that are categorized by product area and can therefore search for either the product or the product area they prefer. Customers also have a part dedicated to shipping so when they buy the goods they pay for through our portal they have the possibility to choose the fastest and cheapest shipping, this related to shipping must be done via API that we connect to the companies of shipping and then through an algorithm they find the most convenient shipping. the customer can chat in live time with the company always through our portal. Company registration is always done via OTP, they can enter their products there their history and their who we are, can receive messages from customers to give life to a negotiation. they too will have access to the shipping area. The admin area is mine that I view everything from my management system. I think that’s all if something is missing we will insert it.
the site must be done in programmed language.
Everything must be included in the price, thanks
