User input form(European only)

The project is to build a small ajax form using jquery / pure js which allows a user to search/ add customers. -The user types an email or phone number. -While typing the script makes ajax requests to an endpoint which searches for existing customers. (will provide json endpoint) -If the user clicks a customer the outlined form elements appear with populated data from the search result. -If the user types a valid phone number or email with no results the outlined form is displayed with blank values. A message show indicate a new customer record is being created. -Form elements have the following names: email,phone,first_name,last_name,street,state,zip,city,subscribed -Form cannot be submitted without a valid email or phone. (one of the two is ok) I will provide API endpoint and existing css file to selected applicants. Please provide a cost estimate.
