Custom page won't show Form

Hi Guys
Thank you for a great plugin.. I have created a custom page in word press with my own header and the form wont show on the page. I must be missing a script in the header. Here is the site and any assistance would be greatly appreciated https://www.hireezy.com/index.php/portfolio/club-ezysoft-responsive/
