Need PHP Expert To Make Contact Form Workable On HTML Website

I've a website which is currently built in HTML, CSS, JS. The website contains a contact form which is built in two steps. First steps collect insights about the investors (like amount they want to invest and other such things). On clicking next, the form asks for details like name, email and phone etc.

I need a PHP expert who can make this contact form workable on my HTML website. The website link is http://naturedelamour.com/bestbonds/

Need someone who is good at PHP and can make this contact form workable real quick for me as it's quite urgent to get it done.
