Design Effective Landing page in Wordpress Website

Create a beautiful landing page in a Wordpress website, where there will be a list of PDF documents that can be downloaded after inserting the visitor's name, address, email, company name and other in a form. The Wordpress landing page exists but it has a bad design. The download feature needs some tweaks, but you must make it work better. The Wordpress landing page must have the same design and colours as the Wordpress website. ---- IMportant: the landing page design must increase the downloads of the promotion PDF documents listed in it (brochure, etc.). The landing page must be designed according to proven marketing techniques that will improve the number of downlodas.
