Hi, there!
We checked the example and we can develop a similar parallax website for you.
We work with CMS Wordpress, HTML5, CSS3, Bootstrap, Php, Javascript, Ajax, Jquery, etc. Have a look at our reviews and information about our team - https://www.freelancer.com/u/Webln .
Could you show graphics, please? We are ready to discuss your project.
With regards,
WebIn team!
