Website with AJAX - READ CAREFULLY

BEFORE BID, READ CAREFULLY Before bidding, pay attention to the description! I need to create a website with the following functions: The user when entering the website must create an account that will take him to an area (user dashboard) where he can create a sub domain, for example, the name of the site will be [login to view URL], then he creates [login to view URL] . In this subdomain he will be able to create a personalized form with various functions such as text areas, radio buttons and etc..., insert logo and other things like a presentation text... But most importantly, the result of sending the form should be sent to WHATSAPP. This is the most important. After the user creates a subdomais and configure the form, he will be sent to a payment page to contratc the service to use.
